In which district of Rajasthan 'Khadin' is a popular method of water conservation?

  1. A.Nagaur
  2. B.Bikaner
  3. C.Jaisalmer
  4. D.Pali

Correct answer

C. Jaisalmer

Explanation

The correct answer is C, Jaisalmer. A khadin is a long earthen embankment built across the lower end of a sloping field, so that rainwater running off the higher rocky ground collects behind it. The water soaks into the soil during the monsoon, and in winter crops such as wheat and gram are grown on the moist bed without any further irrigation, while wells below the bund also get recharged. The system is credited to the Paliwal Brahmins of Jaisalmer, who developed it around the 15th century, and it suits the district's stony, sloping land and very low rainfall. It is one of the best examples of runoff farming in the Thar. Option A is wrong because Nagaur is not the home of the khadin system. Option B is wrong because Bikaner is known for other rainwater structures, such as the kund and the kui. Option D is wrong because Pali, on the eastern side of the Luni basin, is not where khadins developed. Exam tip: khadin, Paliwal Brahmins, Jaisalmer; kund and tanka store rainwater; kui taps seepage water.

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.

  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.
