Which of the following statements about the Black Soils of India is/are correct ? 1. Black Soils cover most of the Deccan Plateau. 2. Also known as 'Regur', they are generally clayey, deep and impermeable. 3. Since they are impermeable, rainfed crops do not grow well in Black Soils. Select the answer using the codes given below :

  1. A.1 and 2 only
  2. B.2 only
  3. C.1, 2 and 3
  4. D.3 only

Correct answer

A. 1 and 2 only

Explanation

The correct answer is A, 1 and 2 only. Black soil covers most of the Deccan Plateau, and its clay holds water so well that rainfed crops actually do well in it, so statement 3 is false. The soil formed from the weathering of the basalt lava of the Deccan Traps and is spread over Maharashtra, Gujarat, western Madhya Pradesh, and parts of Karnataka, Telangana and Andhra Pradesh. It is called regur, and also black cotton soil because cotton is its classic crop. It is clayey, deep and impermeable; it swells and turns sticky when wet and shrinks with wide cracks when dry, which lets air into the lower layers, a kind of self-ploughing. Because it stores moisture for a long time, crops such as cotton, jowar and pulses grow on it without irrigation. Option B is wrong because statement 1 is also correct. Option C is wrong because statement 3 is false. Option D is wrong because statement 3 is the only false one. Exam tip: regur = basalt origin + moisture retention + cotton.

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.
