Streams and rivers coming from the mountains deposit heavy materials of rocks and boulders in

  1. A.Khadar
  2. B.Bhangar
  3. C.Bhabar
  4. D.Terai

Correct answer

C. Bhabar

Explanation

The correct answer is C, Bhabar. When rivers leave the Himalayas and reach the plains, their speed drops suddenly and they drop the heaviest load first, pebbles and boulders, in the Bhabar belt. The Bhabar is a narrow strip about 8 to 16 km wide that runs along the foot of the Shiwaliks from the Indus to the Tista. The ground is so porous that most streams sink underground and seem to disappear here. South of it, the water comes up again and creates the wet, marshy Terai, once covered by thick forests full of wildlife. A is wrong, because Khadar is the newer, fine alluvium of the flood plains, renewed almost every year by floods. B is wrong, because Bhangar is the older alluvium on higher ground above flood level, with lime nodules called kankar. D is wrong, because the Terai lies below the Bhabar and has fine, damp soil where the lost streams re-emerge, not boulders. Exam tip: from the hills down, Bhabar (boulders, streams vanish), Terai (streams return, marshy), then Bhangar old and Khadar new alluvium.

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.

Q3.GeographyAsked in: CDS · CDS-II 2017, GKMedium

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.
