Geography Mixed Quiz: Set 1

The correct answer is B, Venus. Venus is wrapped in a very thick atmosphere of carbon dioxide, which lets sunlight in but does not let the heat escape. This runaway greenhouse effect keeps its surface hotter than that of any other planet, even at night and even on the side turned away from the Sun.

Option A, Mercury, is nearer the Sun and is therefore the usual wrong choice, but it has almost no atmosphere to hold heat, so its nights are bitterly cold. Option C, Mars, is farther away, has a thin atmosphere and is a cold desert planet. Option D, Jupiter, is a gas giant far beyond the asteroid belt and is colder still at its cloud tops. Remember Venus for three records at once: hottest planet, brightest planet in our sky, and the twin of the Earth in size.

The correct answer is B, 1 and 3, that is Bihar and Manipur. The Sun is overhead, with its rays vertical at noon, only at places between the Tropic of Cancer (23.5 degrees N) and the Tropic of Capricorn (23.5 degrees S). The Tropic of Cancer crosses India through eight states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. Any state lying wholly north of this line never gets vertical rays. Bihar stretches roughly from 24.3 to 27.5 degrees N and Manipur from about 23.8 to 25.7 degrees N, so both lie entirely north of the tropic and the Sun is never directly overhead there. A and C are wrong because they include Chhattisgarh, and D is wrong because it includes Rajasthan; the Tropic of Cancer passes through both, so their southern parts do receive vertical rays around 21 June. Exam tip: memorise the eight tropic states, Gujarat, Rajasthan, MP, Chhattisgarh, Jharkhand, West Bengal, Tripura, Mizoram; states such as Bihar, UP, Punjab, Manipur and Assam lie north of the line.

The correct answer is D, metamorphic. Quartzite is formed when sandstone, a sedimentary rock, is changed by great heat and pressure deep inside the earth. The quartz grains of the sandstone recrystallise and fuse, so quartzite becomes one of the hardest and most weather-resistant rocks, which is why the ridges of the Aravalli range and the Delhi Ridge, made largely of quartzite, have survived for hundreds of millions of years. Such change of an existing rock without melting is called metamorphism. A is wrong because igneous rocks such as granite and basalt form from cooled magma or lava, not from an older rock under pressure. B is wrong because basalt is itself a specific igneous rock, not a class of rock. C is wrong because sedimentary is the parent type; sandstone is sedimentary, but once transformed it is no longer classed that way. Exam tip: sandstone becomes quartzite, limestone becomes marble, shale becomes slate, granite becomes gneiss.

The correct answer is D, 1, 2 and 3. All three statements are true. Statement 1: the size of an eruption is rated on the Volcanic Explosivity Index, a scale from 0 to 8 based on the volume of material thrown out and the height of the eruption column; each step up means roughly ten times more material. Statement 2: Iceland sits on the Mid-Atlantic Ridge where two plates move apart, and the Philippines lies on the Pacific Ring of Fire, so both were built by volcanic activity. Statement 3: volcanic ash and lava weather into deep, mineral-rich soils, which is why Java in Indonesia supports dense farming and the Deccan's black soil, formed from basalt lava, grows cotton so well. A is wrong, because it leaves out statement 3, which is true. B is wrong, because it drops statement 1, and the index is the standard measure. C is wrong, because it drops statement 2, though both Iceland and the Philippines are volcanic. Exam tip: VEI runs from 0 to 8; Iceland sits on a ridge, the Philippines on the Ring of Fire; basalt gives black soil.

The correct answer is A, precipitation. Precipitation is any form of water, liquid or solid, that falls from clouds to the ground. When the temperature is above freezing it falls as rain or drizzle; below freezing, water vapour turns directly into ice crystals that fall as snow. Sleet is rain that freezes into small ice pellets while falling through a cold layer of air, and hail is made of hard ice balls built up layer by layer inside towering cumulonimbus clouds during thunderstorms. All three are therefore solid forms of precipitation. B, Condensation, is the change of water vapour into tiny droplets or ice crystals, which forms clouds, dew, frost and fog, but these do not fall from clouds. C, Transpiration, is the loss of water vapour from the leaves of plants. D, Evaporation, is the change of liquid water into vapour, the first step of the water cycle. Exam tip: rain, drizzle, snow, sleet and hail fall, so they are precipitation; dew, frost, fog and mist form on or near the ground, so they are condensation.

The correct answer is A, Tamil Nadu. The Arabian Sea branch of the southwest monsoon strikes the Western Ghats first and drops most of its moisture on the windward western slopes, so the land on the eastern, leeward side gets little rain. This dry leeward zone is the rain shadow, and Tamil Nadu lies in it, which is why it receives its main rain later, from the retreating north-east monsoon in October to December. A famous local example is Mumbai getting far more monsoon rain than Pune, which lies just behind the Ghats. B is wrong because Gujarat is on the windward side and gets direct rain from the Arabian Sea branch. C is wrong because Goa lies on the west coast in front of the Ghats and is one of the wettest states. D is wrong because Kerala is where the southwest monsoon first arrives in India, around 1 June, and it gets very heavy rain. Exam tip: the Western Ghats block the Arabian Sea branch; west side wet (Kerala, Goa), east side dry (Tamil Nadu), which is why Tamil Nadu depends on the north-east monsoon.

The correct answer is B, North Atlantic Ocean. The Sargasso Sea lies in the middle of the North Atlantic and is the only sea in the world with no coastline. Instead of land, it is bounded by four ocean currents that circle clockwise around it: the Gulf Stream on the west, the North Atlantic Current on the north, the Canary Current on the east and the North Atlantic Equatorial Current on the south. Because it sits in the calm centre of this gyre, its water is warm, clear and very salty. It is named after sargassum, a brown seaweed that floats on its surface in huge mats, and it is the breeding ground of the American and European eels. Option A is wrong because the Arctic Ocean lies around the North Pole, far from this sea. Option C is wrong because the Sargasso Sea is north of the equator, not in the South Atlantic. Option D is wrong because the Indian Ocean is on the other side of Africa. Exam tip: Sargasso Sea means North Atlantic, no coastline, walled by currents, named after floating seaweed.

The correct answer is A, Indira point. Indira Point on Great Nicobar Island in the Andaman and Nicobar Islands is the southernmost point of Indian territory, at about 6 degrees 45 minutes north latitude. It was earlier called Pygmalion Point and was renamed after Indira Gandhi in 1985. It lies only about 150 km from Indonesia's Sumatra, and its lighthouse area was partly submerged by the 2004 tsunami. The question asks about the whole territory, which includes the islands, so the mainland tip is not the answer. B is wrong because Kanyakumari is the southernmost point of the Indian mainland, not of the entire territory. D is wrong because Cape Comorin is simply the old English name of Kanyakumari, so it is the same mainland point. C is wrong because Karondi is not a recognised geographical extremity of India. Exam tip: southernmost point of India is Indira Point (Great Nicobar); southernmost point of the mainland is Kanyakumari (Cape Comorin).

The correct answer is D, Zoji La. Zoji La is the pass on the Srinagar–Leh highway (NH 1) that joins the Kashmir valley with Dras and Ladakh. It sits at about 3,528 metres in the Great Himalayan range and stays snowbound for months every winter, which is why the Zojila tunnel is being built to keep Ladakh connected all year. Kargil and Dras lie just beyond it, so the pass mattered a great deal during the 1999 Kargil conflict. A is wrong because Nathu La is in Sikkim on the border with Tibet (China) and is used for the Kailash Mansarovar route and border trade. B is wrong because Bara-lacha La is in Himachal Pradesh on the Manali–Leh road, not the Srinagar road. C is wrong because Jelep La is also a Sikkim–Tibet pass, close to Nathu La. Exam tip: Srinagar–Leh means Zoji La; Manali–Leh means Rohtang and Bara-lacha La; Sikkim means Nathu La and Jelep La.

The correct answer is D, Tamil Nadu. The Shevaroy Hills, also spelt Servarayan, rise near Salem in Tamil Nadu and are part of the Eastern Ghats. Their best-known spot is the hill station of Yercaud, about 1,500 metres high, famous for coffee plantations, oranges and the Yercaud lake, which is why the range is sometimes called the "poor man's Ooty". The Shevaroys form a set with the other Eastern Ghats hills of Tamil Nadu, the Javadi, Kalrayan and Pachaimalai hills, and all four sit between the Palar and Kaveri river basins. A, Chhattisgarh, has the Maikal range and the Bastar plateau. B, Odisha, has the Garhjat hills and Mahendragiri in its stretch of the Eastern Ghats. C, Rajasthan, has the Aravalli range with Guru Shikhar as its highest point. Exam tip: Shevaroy, Javadi, Kalrayan and Pachaimalai are Tamil Nadu's Eastern Ghats hills; Yercaud sits on the Shevaroys.

The correct answer is A, Brahmaputra. Majuli lies in the Brahmaputra river in Assam, near Jorhat, and is the largest river island in the world. In 2016 it became India's first island district. It is the heart of Assam's neo-Vaishnavite culture: the saint Srimanta Sankardeva and his disciple Madhavdeva set up satras (monasteries) there in the 15th and 16th centuries, and the island is famous for its mask-making and the Raas festival. Every monsoon the Brahmaputra eats away its banks, so Majuli has shrunk from over 1,200 square km to less than half of that, making erosion its biggest worry. B is wrong because the Ganga has no comparable island; its delta islands such as Sagar belong to the Sundarbans. C is wrong because the Indus flows mainly through Pakistan and has no such island. D is wrong because the Godavari's Konaseema is a delta region, not a single river island. Exam tip: Majuli equals Brahmaputra equals Assam, first island district of India (2016).

The correct answer is D, Vembanad Lake. Vembanad in Kerala is the longest lake in India, stretching about 96 km from Alappuzha to Kochi, and it is also the largest lake of Kerala. It is a brackish backwater lagoon separated from the Arabian Sea by a narrow barrier, it is a Ramsar wetland since 2002, and the famous Nehru Trophy snake-boat race is held on it at Punnamada every August. Willingdon Island, on which Kochi port stands, was raised inside this lake. A, Shivaji Sagar Lake, is the reservoir of the Koyna dam in Maharashtra, a man-made lake. B, Indira Sagar, is the reservoir of the Indira Sagar dam on the Narmada in Madhya Pradesh, the largest reservoir in India by water volume but not the longest lake. C, Chilika Lake in Odisha is the largest brackish-water lagoon in India and Asia by area, but it is shorter than Vembanad. Exam tip: longest lake Vembanad, largest brackish lagoon Chilika, largest freshwater lake Wular.

The correct answer is B, fissure volcanic rock. Black cotton soil, or regur, formed from the weathering of the Deccan Trap basalt, lava that poured out through long cracks in the crust about 65 million years ago. This fissure eruption spread layer after layer of basalt over Maharashtra, western Madhya Pradesh, Gujarat and parts of Karnataka, Telangana and Andhra Pradesh, and the soil is found mainly on this plateau. It is rich in iron, lime, magnesium and potash but poor in nitrogen, phosphorus and organic matter, and its dark colour comes from titaniferous magnetite and humus. It holds moisture well, swells when wet and cracks deeply when dry, so it is said to 'plough itself', and it suits cotton. Option A is wrong because brown forest soil is itself a soil type, not the parent rock of regur. Option C is wrong because granite and schist weather mainly into red soils. Option D is wrong because shale and limestone are sedimentary rocks, not the source of the Deccan soils. Exam tip: regur means Deccan basalt, cotton and self-ploughing cracks.

The correct answer is C, Neither I nor II. Both pairs are reversed: in Punjab rice is a commercial crop, while in Odisha it is a subsistence crop. The same crop can be commercial in one state and subsistence in another; it depends on why the farmer grows it. A subsistence crop feeds the farmer's own family, and a commercial crop is grown mainly for sale. Punjab and Haryana farmers do not eat much rice, yet they grow it on irrigated land with high-yielding seeds and sell almost all of it to the government at the minimum support price. In Odisha, West Bengal and Assam rice is the staple food, grown mostly on small rain-fed plots for the family's own kitchen. A is wrong because Punjab rice is sold, not eaten at home, so it is commercial. B is wrong because Odisha rice is largely eaten by the growers, so it is subsistence. D fails because neither pair is correct. Exam tip: NCERT line to remember, rice is commercial in Punjab and Haryana but subsistence in Odisha.

The correct answer is D, Titanium. Ilmenite (FeTiO3) and rutile (TiO2) are the main ores of titanium, and India has large deposits of them in its beach sands. These heavy mineral sands occur mainly along the coasts of Kerala (Chavara), Tamil Nadu (Manavalakurichi) and Odisha (Chhatrapur), often together with monazite, zircon and garnet. Titanium is light, strong and does not rust, so it is used in aircraft, spacecraft and medical implants, while titanium dioxide is the white pigment in paints, paper and toothpaste. Option A is wrong because aluminium comes from bauxite, found mainly in Odisha and Jharkhand. Option B is wrong because copper comes from ores like chalcopyrite, mined at Khetri in Rajasthan and Malanjkhand in Madhya Pradesh. Option C is wrong because iron is taken from haematite and magnetite; ilmenite does contain iron, but it is mined for its titanium. Exam tip: ilmenite and rutile give titanium, monazite gives thorium and rare earths, and all three come from the black sands of the south-west and east coasts.

The correct answer is A, Waterways. Water transport needs no track or road to be built, and a ship or barge can carry huge loads on little fuel, so the cost per tonne is the lowest. That is why coal, iron ore, food grains, cement and containers travel across oceans and along rivers and canals in ships and barges. NCERT's geography textbook calls waterways the cheapest way of carrying heavy and bulky goods over long distances. India's inland waterways, such as National Waterway 1 on the Ganga from Prayagraj to Haldia, use the same idea. The price paid for the low cost is slow speed. B is wrong because railways are cheaper than roads for bulk goods but still cost more than waterways. C is wrong because airways are the fastest but the costliest, and suit light and valuable goods. D is wrong because roadways are best for short distances and door-to-door delivery. Exam tip: cheapest, waterways; fastest, airways; door-to-door, roadways.

The correct answer is D, 74.04%. This is the overall literacy rate the Census of 2011 reported for India, the figure used in textbooks and exam papers. The Census counts a person aged seven or above who can read and write with understanding in any language as literate, so small children are left out. The same Census gave 82.14 percent for males and 65.46 percent for females, and the paper has cleverly put both of those numbers in the options. Kerala was the most literate state and Bihar the least. A is wrong because 16.68 is the gap between the male and female rates (82.14 minus 65.46), not a literacy rate at all. B is wrong because 65.46 percent is the female literacy rate of 2011, not the overall rate. C is wrong because 82.14 percent is the male literacy rate of 2011. Exam tip: Census 2011 literacy is 74.04 overall, 82.14 male and 65.46 female; the overall figure always lies between the two.

The correct answer is D, Manipur. Nepal touches five Indian states: Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim. Manipur lies far to the east in the North-East and shares its international border only with Myanmar. Bihar has the longest border with Nepal, and the India-Nepal border is an open border of about 1,750 km along which people move without a visa. Two easy memory hooks: the Kali river separates Uttarakhand from Nepal, and the Siliguri corridor of West Bengal lies between Nepal and Bangladesh. A is wrong because Sikkim lies between Nepal and Bhutan and shares its western border with Nepal. B is wrong because Bihar has the longest boundary with Nepal among all states. C is wrong because the Darjeeling district of West Bengal borders eastern Nepal. Exam tip: Nepal's five neighbours are Uttarakhand, UP, Bihar, West Bengal and Sikkim; Manipur, Mizoram, Nagaland and Arunachal touch Myanmar.

The correct answer is A, Borneo. Of the four islands listed, Borneo has the largest area; it is the third-largest island in the world and the largest in Asia. The world's top islands by area run Greenland, New Guinea, Borneo, Madagascar, Baffin and Sumatra, with Australia counted as a continent rather than an island. Borneo lies in South-East Asia and is the only island shared by three countries: Indonesia, whose part is called Kalimantan, Malaysia, with Sabah and Sarawak, and the small nation of Brunei. Option B is wrong because Great Britain, though the largest island in Europe, ranks only around ninth in the world. Option C is wrong because Madagascar, off the east coast of Africa, is the fourth-largest, just behind Borneo. Option D is wrong because Sumatra, also in Indonesia, is sixth, well behind Borneo. Exam tip: remember the top four as Greenland, New Guinea, Borneo, Madagascar, and that Borneo belongs to three countries.

The correct answer is A, Orange River. The Orange River is the longest river of South Africa, about 2,200 km long. It rises in the Drakensberg mountains of Lesotho, flows west across South Africa and falls into the Atlantic Ocean at Alexander Bay. For part of its course it forms the border between South Africa and Namibia. Its main tributary is the Vaal, and the Augrabies Falls lie on the Orange. The Limpopo is the other big river of South Africa, flowing east into the Indian Ocean. B is wrong because the Nile, the longest river in the world, flows north through countries such as Uganda, Sudan and Egypt into the Mediterranean Sea. C is wrong because the Congo flows through Central Africa, crosses the Equator twice and enters the Atlantic. D is wrong because the Niger flows through West Africa (Guinea, Mali, Niger and Nigeria) into the Gulf of Guinea. Exam tip: South Africa = Orange and Limpopo; Nile = north-east Africa; Congo = crosses the Equator twice; Niger = West Africa; Zambezi = Victoria Falls.
