Match the following columns and choose the correct option. Column I: (a) Marble, (b) Sandstone, (c) Coal, (d) Granite. Column II: (i) Sedimentary rocks, (ii) Fossil fuels, (iii) Igneous rocks, (iv) Metamorphic rocks.

  1. A.(a) - (iv), (b) - (i), (c) - (ii), (d) - (iii)
  2. B.(a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
  3. C.(a) - (i), (b) - (iv), (c) - (iii), (d) - (ii)
  4. D.(a) - (iii), (b) - (ii), (c) - (i), (d) - (iv)

Correct answer

A. (a) - (iv), (b) - (i), (c) - (ii), (d) - (iii)

Explanation

The correct answer is A, (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii). Marble is a metamorphic rock, formed when limestone is changed deep inside the earth by great heat and pressure; the Taj Mahal is built of it. Sandstone is a sedimentary rock, made of sand grains carried by wind or water and pressed together in layers over long periods, and it is the red stone of Fatehpur Sikri. Coal is counted as a fossil fuel, formed from plant remains buried in swamps millions of years ago and slowly changed by heat and pressure. Granite is an igneous rock, formed when molten magma cools and hardens below the surface, which gives it a coarse, grainy look and great hardness. B, C and D are wrong because each swaps at least two of these pairs, most often putting granite with sedimentary rocks or marble with igneous rocks. Exam tip: limestone becomes marble, magma gives granite, sand gives sandstone.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude. Select the correct answer using the code given below.

  1. A.1 and 2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
