General Knowledge Questions and Answers - Geography

1. Which is the longest river in India?

1. Yamuna river
2. Godavari river
3. Ganga river
4. Brahmaputra river

Answer: C) Ganga river

Explanation: The Ganga is the longest river in India, flowing for about 2,525 kilometers from its source to its mouth. It originates from the Gangotri Glacier in the Uttarakhand state, where it is initially known as the Bhagirathi. The Bhagirathi meets the Alaknanda at Devprayag in Uttarakhand, and from there, the river is officially called the Ganga. The Ganga flows through the states of Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal before entering Bangladesh. It empties into the Bay of Bengal, forming the world's largest delta — the Sundarbans Delta. Ganga River Basin is the largest river basin in India, covering about 26% of the country’s land area. Major cities located on the banks of the Ganga include Haridwar, Kanpur, Allahabad (Prayagraj), Varanasi, Patna, and Kolkata. Although the Indus River is longer overall, only a part of it flows through India. The Ganga is the longest river that flows entirely within India.

7. Which is the most fertile soil found in the northern plains of India?

1. Black Soil
2. Red Soil
3. Laterite Soil
4. Alluvial Soil

Answer: D) Alluvial Soil

Explanation: Alluvial soil is the most fertile soil found in the northern plains of India, particularly in the Indo-Gangetic-Brahmaputra plains. It is formed by the deposition of silt, sand, and clay carried by rivers such as the Ganga, Indus, and Brahmaputra and their tributaries. Alluvial soils are rich in essential minerals like potash, lime, and phosphoric acid, which make them highly fertile and suitable for agriculture. They are especially good for the cultivation of crops such as wheat, rice, sugarcane, maize, pulses, and oilseeds. Based on age, alluvial soils are of two types: 1.Khadar: New alluvium, found near riverbeds, more fertile and renewed by floods every year 2.Bhangar: Older alluvium, found on higher terraces, less fertile due to calcareous deposits called kankar. They cover about 40% of India’s total land area, making them the most widespread soil in the country. The northern plains are considered the “food bowl of India” mainly because of the fertility of alluvial soil.

8. Which soil is rich in iron but poor in nutrients like nitrogen and phosphorus?

1. Black Soil
2. Red Soil
3. Alluvial Soil
4. Laterite Soil

Answer: B) Red Soil

Explanation: Red soil is rich in iron oxide, which gives it a reddish color. It is generally poor in essential nutrients like nitrogen, phosphorus, and humus, making it less fertile compared to alluvial soil. Red soil develops from the weathering of igneous and metamorphic rocks, particularly granite and gneiss. Its color varies: it is red when well-drained and may appear yellowish when it contains more hydrated ferric oxides. It is generally found in southern and eastern India, including states like Tamil Nadu, Karnataka, Andhra Pradesh, Odisha, Chhattisgarh, Jharkhand, and parts of Maharashtra and Madhya Pradesh. Despite being low in fertility, red soil can be made productive with the use of fertilizers and irrigation. It is suitable for crops such as cotton, pulses, millets, tobacco, oilseeds, potatoes, and some fruits. Red soil is generally sandy to clayey in texture, with good drainage but poor water retention capacity.

9. The Gandak river is a tributary of which river?

1. Yamuna river
2. Brahmaputra river
3. Ganga river
4. Son river

Answer: C) Ganga river

Explanation: The Gandak River is an important tributary of the Ganga River. It originates from the Nepal Himalayas, specifically near the Tibetan plateau between Dhaulagiri and Everest ranges. In Nepal, the river is also known as the Kali Gandaki, famous for its deep gorge called the Kali Gandaki Gorge, one of the deepest in the world. The Gandak enters India in Bihar, and it flows through the northern plains before joining the Ganga River near Patna. The total length of the Gandak River is about 630 km, out of which a major portion flows through Nepal before entering India. The river passes through important Indian districts such as West Champaran, East Champaran, Muzaffarpur, Gopalganj, and Saran. It is used for irrigation, agriculture, and hydropower projects, both in Nepal and India. The Gandak is also significant for the Gandak Canal Project, which provides irrigation facilities to Bihar and Uttar Pradesh.

10. Tsang Po and Jamuna are other names of which river?

1. Brahmaputra river
2. Ganga river
3. Yamuna river
4. Indus river

Answer: A) Brahmaputra river

Explanation: The Brahmaputra River is known by different names in different regions: In Tibet, it is called the Tsangpo (or Yarlung Tsangpo). In Bangladesh, it is known as the Jamuna. The river originates from the Chemayungdung Glacier in the Kailash Range, Tibet, near Lake Mansarovar. It flows eastward through Tibet as the Yarlung Tsangpo, carving one of the world’s deepest gorges — the Yarlung Tsangpo Grand Canyon. The river enters India through Arunachal Pradesh, where it is called the Siang (or Dihang). In Assam, it is widely known as the Brahmaputra, flowing through the fertile Brahmaputra valley. After entering Bangladesh, the river splits and is called the Jamuna, before finally merging with the Ganga (Padma) and Meghna rivers to form the world’s largest delta — the Sundarbans Delta. The total length of the Brahmaputra is about 2,900 km, making it one of the major rivers of South Asia. It is a transboundary river, flowing through China (Tibet), India, and Bangladesh. The Brahmaputra is known for its floods and shifting channels, especially in Assam and Bangladesh, but it also provides fertile soil for agriculture.

11. As of 2025, which state in India has the highest number of districts?

1. Uttar Pradesh
2. Madhya Pradesh
3. Rajasthan
4. Bihar

Answer: A) Uttar Pradesh

Explanation: Uttar Pradesh has the largest number of districts in India, with 75 districts as of early 2025. Uttar Pradesh is followed by Madhya Pradesh, which has 55 districts. Bihar has 38 districts, which is significantly lower than Uttar Pradesh’s count. The high number of districts in Uttar Pradesh reflects its large population, vast geographic area, and administrative complexity, necessitating finer administrative divisions for effective governance. Uttar Pradesh is the most populous state in India, so having 75 districts helps the state government manage administration, law and order, and development schemes more effectively. The largest district in Uttar Pradesh by area is Lakhimpur Kheri, while the smallest by area is Hapur. The latest district created in Uttar Pradesh is Hapur (2012), carved out of Ghaziabad district.

General Knowledge Questions and Answers - History

1. Which is the oldest empire in India?

1. Mauryan Empire
2. Gupta Empire
3. Mughal Empire
4. Magadha Empire

Answer: A) Mauryan Empire

Explanation: The Mauryan Empire (322 BCE – 185 BCE) is considered the first and oldest major empire in India because it was the first to unify almost the entire Indian subcontinent under one central authority. It was founded by Chandragupta Maurya in 322 BCE, after overthrowing the Nanda dynasty of Magadha with the guidance of Chanakya (Kautilya). The empire reached its greatest extent under Ashoka the Great (268–232 BCE), covering nearly the entire Indian subcontinent except parts of Tamil Nadu and Kerala, and extended into present-day Afghanistan. The capital of the Mauryan Empire was Pataliputra (modern-day Patna, Bihar). The empire had an efficient administration, centralized government, and one of the world’s largest standing armies of the time. The Arthashastra, written by Chanakya (Kautilya), provides details about Mauryan administration, economy, and military strategy. Ashoka’s reign is especially remembered for the spread of Buddhism within and outside India (Sri Lanka, Central Asia, Southeast Asia). The Mauryan Empire declined after Ashoka’s death and finally ended in 185 BCE, when the last ruler Brihadratha Maurya was assassinated by his general Pushyamitra Shunga, who established the Shunga dynasty.

2. Who ruled the first Indian empire?

1. Ashoka
2. Samudragupta
3. Harshavardhana
4. Chandragupta Maurya

Answer: D) Chandragupta Maurya

Explanation: The first Indian empire was the Mauryan Empire (322 BCE – 185 BCE), and it was founded and ruled by Chandragupta Maurya. Chandragupta Maurya established the empire in 322 BCE after defeating the Nanda dynasty of Magadha with the guidance and strategy of his mentor Chanakya (Kautilya). He became the first emperor to unify most of northern India under a centralized administration, making the Mauryan Empire the first pan-Indian empire. The capital of the Mauryan Empire was Pataliputra (modern-day Patna, Bihar), which became a major political, cultural, and economic center. Chandragupta’s administration was well-organized, with separate departments for taxation, trade, agriculture, and military, as described in Kautilya’s Arthashastra. He created one of the largest standing armies of the ancient world, ensuring strong defense and expansion of the empire. Chandragupta expanded the empire westward by defeating Seleucus I Nicator, a Greek general of Alexander the Great, in 305 BCE. As part of the peace treaty, Chandragupta gained territories in present-day Afghanistan, Baluchistan, and parts of Iran. Toward the end of his life, Chandragupta Maurya abdicated the throne, became a Jain monk, and spent his last years at Shravanabelagola (Karnataka), where he is believed to have died by Sallekhana (ritual fast unto death). Later rulers of the Mauryan dynasty included Bindusara (his son) and Ashoka the Great (his grandson).

3. Who wrote the Mauryan book Arthashastra?

1. Chanakya
2. Ashoka
3. Chandragupta Maurya
4. Kalidasa

Answer: A) Chanakya

Explanation: The Arthashastra is an ancient Indian treatise on statecraft, administration, military strategy, economics, and law. It was written by Chanakya (also known as Kautilya or Vishnugupta), who was the chief advisor and mentor of Chandragupta Maurya, the founder of the Mauryan Empire. The Arthashastra provides detailed instructions on how a king should rule, covering topics such as governance, diplomacy, taxation, agriculture, trade, defense, foreign relations, and justice. The book emphasizes the idea of “Matsya Nyaya” (law of the fish), meaning in the absence of strong governance, the big fish (strong) would eat the small fish (weak). Hence, a strong state is necessary for order. It advocates the use of danda (punishment/force) and diplomatic strategies (sama, dana, bheda, danda) for maintaining power and control. The Arthashastra was rediscovered in 1904 by R. Shamasastry, who later translated it into English, bringing it to modern attention. The work is divided into 15 books (Adhikaranas), covering different aspects of administration and warfare. The text highlights advanced ideas such as espionage, fortifications, military organization, and economic policies, making it one of the most sophisticated political works of the ancient world. Chanakya used the principles of the Arthashastra to help Chandragupta Maurya overthrow the Nanda dynasty and establish the Mauryan Empire.

4. Chanakya was also known as:

1. Kalidasa
2. Banabhatta
3. Vishnugupta
4. Tulsidas

Answer: C) Vishnugupta

Explanation: Chanakya, the famous teacher, philosopher, and royal advisor of ancient India, was also known by two other names: Kautilya and Vishnugupta. He played a crucial role in the establishment of the Mauryan Empire by helping Chandragupta Maurya overthrow the Nanda dynasty in Magadha. The name Vishnugupta is mentioned in the concluding verse of his famous work Arthashastra, confirming that it was written by him. Chanakya is considered the pioneer of political science and economics in India, and his principles of governance, diplomacy, and warfare are still studied today. His strategy, wisdom, and policies earned him the title of the “Indian Machiavelli”, though his ideas predate Machiavelli by nearly 1800 years. He founded Takshashila University’s political and economics teachings, making him one of the earliest and most influential teachers in history.

5. Who was the first Governor-General of India?

1. Lord Mountbatten
2. Lord William Bentick
3. Lord Canning
4. Robert Clive

Answer: B) Lord William Bentick

Explanation: Lord William Bentinck was the first Governor-General of India from 1833 to 1835, after the Charter Act of 1833 converted the title of Governor-General of Bengal to Governor-General of India. Before him, the post of Governor-General of Bengal existed, which was held by officials like Warren Hastings and Lord Cornwallis. The Charter Act of 1833 made the Governor-General of Bengal the Governor-General of all British territories in India, centralizing administration. Bentinck is remembered as a liberal reformer who introduced significant social, administrative, and financial reforms. He is best known for the abolition of Sati (1829), which was a major social reform carried out with the support of Raja Ram Mohan Roy. He also suppressed Thuggee (organized robbery and murder by Thugs) and worked to improve law and order in British India. In education, Bentinck promoted English education in India, and his tenure laid the foundation for the Macaulay’s Minute on Education (1835), which introduced English as the medium of instruction. His policies focused on economy and efficiency, including cutting down military expenditure and streamlining revenue collection.

6. Which was the first Indian kingdom to accept Buddhism?

1. Mauryan Empire
2. Gupta Empire
3. Magadha Kingdom
4. Chola Empire

Answer: A) Mauryan Empire

Explanation: The Mauryan Empire (322 BCE – 185 BCE) was the first Indian empire to accept and promote Buddhism. Although Chandragupta Maurya founded the empire, it was Emperor Ashoka (273 BCE – 232 BCE), his grandson, who officially embraced Buddhism after the Kalinga War (261 BCE). Deeply moved by the massive loss of life in the war, Ashoka renounced violence and adopted the principles of Dhamma (righteousness) based on Buddhist teachings. Ashoka became one of the greatest patrons of Buddhism in history, spreading the religion not only within India but also to Sri Lanka, Central Asia, Southeast Asia, and the Mediterranean region through missionaries. He built Buddhist stupas, monasteries, and pillars, such as the Sanchi Stupa and Ashokan Pillars, inscribed with edicts that promoted non-violence, tolerance, and moral conduct. The Third Buddhist Council (c. 250 BCE) was convened under Ashoka’s reign at Pataliputra, which helped in codifying Buddhist scriptures and sending missions abroad.

7. Which is called First War of Independence?

1. Quit India Movement – 1942
2. Non-Cooperation Movement – 1920
3. Revolt of 1857
4. Civil Disobedience Movement – 1930

Answer: C) Revolt of 1857

Explanation: The Revolt of 1857 is regarded as the First War of Independence in India because it was the first large-scale and united uprising against British rule. The revolt began on 10th May 1857 in Meerut, when Indian sepoys (soldiers) of the British East India Company mutinied against their officers. The immediate cause was the introduction of Enfield rifles, whose cartridges were rumored to be greased with cow and pig fat—deeply offensive to both Hindu and Muslim soldiers. The revolt quickly spread to other parts of northern and central India, including Delhi, Kanpur, Lucknow, Jhansi, and Gwalior. Important leaders of the revolt included Rani Lakshmibai of Jhansi, Tantia Tope, Nana Saheb, Kunwar Singh, Begum Hazrat Mahal, and Bahadur Shah II (the last Mughal emperor). Although the revolt was suppressed by 1858 due to lack of unity, poor organization, and superior British resources, it marked a turning point in Indian history. After the revolt, the British Crown took direct control of India from the East India Company through the Government of India Act, 1858.

8. Who is the founder of the Indian National Army?

1. Subhas Chandra Bose
2. Lala Lajpat Rai
3. Mohan Singh
4. Bal Gangadhar Tilak

Answer: C) Mohan Singh

Explanation: The Indian National Army (INA) was first formed in 1942 in Singapore by Captain Mohan Singh, an Indian officer in the British Indian Army who was captured by the Japanese during World War II. After his capture, Mohan Singh agreed to cooperate with the Japanese forces and decided to form an army with Indian prisoners of war (POWs) to fight against the British for India’s independence. This first INA, under Mohan Singh’s leadership, aimed to liberate India by supporting Japanese advances into British-held territories. However, differences arose between Mohan Singh and the Japanese authorities, leading to the disbandment of his INA by the end of 1942. Later in 1943, Subhas Chandra Bose reorganized and revitalized the INA after taking command in Singapore, turning it into a much stronger and disciplined force. Under his leadership, INA became famous with the slogan “Give me blood, and I will give you freedom.” The INA fought alongside the Japanese in campaigns in Burma (Myanmar), Imphal, and Kohima, though it ultimately failed due to lack of resources and Japanese defeat in World War II. The INA trials (1945–46) at the Red Fort in Delhi gained widespread attention and fueled nationalist sentiment, becoming a major step toward India’s independence.

9. Who gave the slogan "Give me blood and I will give you freedom"?

1. Mahatma Gandhi
2. Subhas Chandra Bose
3. Jawaharlal Nehru
4. Bhagat Singh

Answer: B) Subhas Chandra Bose

Explanation: The famous slogan “Give me blood, and I will give you freedom” was given by Netaji Subhas Chandra Bose in 1944 during a speech to the Indian National Army (INA) in Burma (now Myanmar). The slogan was a powerful call to arms, urging Indians to sacrifice and fight against British colonial rule to achieve independence. Bose believed that freedom could not be obtained through non-violence alone; it required courage, struggle, and bloodshed if necessary. Subhas Chandra Bose played a leading role in organizing and strengthening the Indian National Army (INA) after taking charge in 1943 in Singapore. Under his leadership, INA fought alongside the Japanese against the British in campaigns in Imphal and Kohima. Bose also established the Provisional Government of Free India (Azad Hind Government) in 1943 in Singapore, which received recognition from several countries. His slogan inspired countless Indians, adding momentum to the national movement and creating a spirit of sacrifice among youth.

10. Who founded the Indian National Congress?

1. Bal Gangadhar Tilak
2. A. O. Hume
3. Dadabhai Naoroji
4. Gopal Krishna Gokhale

Answer: B) A. O. Hume

Explanation: The Indian National Congress (INC) was founded in 1885 by Allan Octavian Hume (A. O. Hume), a retired British civil servant. The first session of the INC was held in Bombay (now Mumbai) from 28th to 31st December 1885, and it was presided over by Womesh Chunder Bonnerjee (W. C. Bonnerjee). The Congress was established with the aim of providing a platform for educated Indians to voice their concerns and to create a sense of political unity among Indians. Initially, INC worked in a moderate manner, using petitions, meetings, and discussions to demand reforms from the British government. Hume played a crucial role as a mediator between Indians and the British, and because of this, he is often called the “Father of the Indian National Congress.” Some Indian leaders like Dadabhai Naoroji, Gopal Krishna Gokhale, and Surendranath Banerjee were early prominent members of the INC, shaping its direction. Over time, the INC became the principal organization leading India’s freedom struggle against British colonial rule, eventually under leaders like Bal Gangadhar Tilak, Mahatma Gandhi, Jawaharlal Nehru, and Subhas Chandra Bose.

General Knowledge Questions and Answers - Science

1. What is the largest organ in the human body?

1. Liver
2. Heart
3. Skin
4. Lungs

Answer: C) Skin

Explanation: The skin is the largest organ of the human body, covering an average area of 1.5 to 2 square meters in adults. It accounts for around 16% of total body weight, making it the heaviest organ as well. The skin acts as the first line of defense against pathogens, harmful chemicals, and physical injuries. It plays a vital role in regulating body temperature through sweating and blood flow control. The skin has three main layers: epidermis (outermost), dermis (middle), and hypodermis (innermost). It contains sensory receptors that help in detecting touch, heat, cold, and pain. The skin also helps in the synthesis of Vitamin D when exposed to sunlight. Apart from protection, it maintains water balance and prevents dehydration.

2. How many bones are there in the human body?

1. 206
2. 210
3. 201
4. 208

Answer: A) 206 bones

Explanation: The human skeleton is made up of 206 bones in adulthood. A newborn baby has about 270 bones, but many of them fuse together during growth. The human skeleton is divided into two main parts: 1.Axial Skeleton (80 bones) includes the skull, vertebral column, and rib cage 2.Appendicular Skeleton (126 bones) includes the bones of arms, legs, shoulders, and pelvic girdle. The longest bone in the human body is the femur (thigh bone). The smallest bone is the stapes bone in the middle ear. Bones are made up of a dense form of connective tissue containing calcium and phosphorus. Bones provide protection to internal organs, for example, the skull protects the brain and the rib cage protects the heart and lungs. Bones also play an important role in the production of blood cells (in bone marrow) and storage of minerals.

3. Which is the largest bone in the human body?

1. Tibia
2. Femur
3. Humerus
4. Pelvis

Answer: B) Femur (Thigh Bone)

Explanation: The femur is the longest, heaviest, and strongest bone in the human body. It connects the hip joint (pelvis) to the knee joint, forming the main structure of the thigh. The average adult femur is about 18–19 inches (45–48 cm) in length. The femur supports the entire body weight when standing and during locomotion. The femur is essential for walking, running, and jumping, providing leverage and mobility. Because it is very dense and strong, it is also the least likely bone to break, though fractures may occur due to severe trauma. In addition to support, the femur contains bone marrow, which helps in the production of blood cells.

4. Which is the largest cell in the human body?

1. Nerve cell
2. Muscle cell
3. Liver cell
4. Ovum

Answer: D) Ovum (female gamete)

Explanation: The ovum (egg cell) is the largest cell in the human body, measuring about 100 micrometers (0.1 mm) in diameter. It is a female reproductive cell (gamete) that combines with the male gamete (sperm cell) during fertilization to form a zygote. The large size of the ovum allows it to store nutrients and cytoplasmic materials that support the initial stages of embryonic growth. The ovum is spherical in shape and is visible to the naked eye without a microscope. A female is born with around 1–2 million immature ova, but only about 400–500 mature and are released during her reproductive lifetime. While the ovum is the largest cell, the sperm cell is the smallest cell in the human body. The ovum is produced in the ovaries and is released during ovulation. Fertilization usually occurs in the fallopian tube, where the ovum meets the sperm.

5. Which is the longest cell in the human body?

1. Muscle cell
2. Nerve cell
3. Bone cell
4. Blood cell

Answer: B) Nerve cell

Explanation: The nerve cell (neuron) is the longest cell in the human body, with some extending up to 100 cm (1 meter). A neuron consists of three main parts: 1.Cell body (soma) contains the nucleus and cytoplasm 2.Dendrites is a Branch-like structures that receive signals from other neurons 3.Axon is A long fiber that carries signals away from the cell body. The length of a neuron is mainly due to its axon, which can stretch from the spinal cord to the toes in humans. Neurons are responsible for carrying messages in the form of electrical impulses throughout the nervous system. They play a key role in sensation, movement, memory, and reflex actions. The human brain contains about 86 billion neurons, making the nervous system highly complex. Neurons do not usually divide or regenerate easily, which is why nerve injuries often take a long time to heal. While neurons are the longest cells, they are not the largest — that title belongs to the ovum.

6. Who discovered penicillin?

1. Louis Pasteur
2. Robert Koch
3. Alexander Fleming
4. Edward Jenner

Answer: C) Alexander Fleming

Explanation: Penicillin, the world’s first true antibiotic, was discovered by Alexander Fleming in 1928. While working at St. Mary’s Hospital in London, Fleming observed that a mold called Penicillium notatum (now Penicillium chrysogenum) accidentally contaminated one of his Petri dishes containing staphylococcus bacteria. He noticed that the bacteria around the mold were destroyed, while those farther away remained unharmed. This observation led him to identify penicillin as a substance capable of killing or inhibiting the growth of many harmful bacteria. His discovery revolutionized medicine and became the foundation of modern antibiotics.

7. How many chambers does the human heart have?

1. Four
2. Two
3. Five
4. Three

Answer: A) Four

Explanation: The human heart is a muscular organ responsible for pumping blood throughout the body. It is divided into four chambers - Two atria (upper chambers): Right atrium and left atrium - Two ventricles (lower chambers): Right ventricle and left ventricle. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body. This double circulation system ensures continuous supply of oxygen and nutrients to tissues while removing carbon dioxide and waste products.

8. Which gas do plants absorb from the atmosphere?

1. Oxygen
2. Carbon Dioxide
3. Nitrogen
4. Hydrogen

Answer: B) Carbon Dioxide

Explanation: Plants absorb carbon dioxide (CO₂) from the atmosphere mainly through small openings on the leaves called stomata. Using this carbon dioxide, along with water absorbed by roots and sunlight, plants perform photosynthesis. In photosynthesis, plants convert carbon dioxide and water into glucose (food) and release oxygen as a by-product. This process is crucial for life on Earth, as it maintains the oxygen–carbon dioxide balance in the atmosphere.

9. What color is chlorophyll?

1. Red
2. Blue
3. Yellow
4. Green

Answer: D) Green

Explanation: Chlorophyll is a green pigment found in the chloroplasts of plant cells. It appears green because it absorbs red and blue wavelengths of light from the visible spectrum and reflects green light, which makes leaves look green to our eyes. Chlorophyll plays a crucial role in photosynthesis, as it captures light energy from the sun and converts it into chemical energy, which is used to produce food (glucose) for the plant.

10. What is the term for molten rock after it erupts from a volcano?

1. Magma
2. Lava
3. Basalt
4. Granite

Answer: B) Lava

Explanation: Molten rock beneath the Earth’s surface is called magma. When this magma rises through volcanic vents and erupts onto the Earth’s surface, it is called lava. Lava is extremely hot, ranging between 700°C and 1200°C. Once lava comes out, it cools and solidifies to form different types of igneous rocks such as basalt (from rapid cooling on the surface) or granite (from slow cooling beneath the surface). Lava flows shape landscapes, create volcanic islands (like Hawaii), and contribute to fertile soil after weathering. Thus, the correct term for molten rock after eruption is lava.
