The north-west part of India receives rainfall in winter due to __________.

  1. A.the south-west monsoon
  2. B.the north-east monsoon
  3. C.western disturbance
  4. D.the retreating of the monsoon

Correct answer

C. western disturbance

Explanation

The correct answer is C, western disturbance. Western disturbances are low-pressure systems that start over the Mediterranean Sea and are carried east towards India by the westerly jet stream in winter. They bring light rain to Punjab, Haryana, Delhi and western Uttar Pradesh, and snowfall to Jammu and Kashmir, Himachal Pradesh and Uttarakhand. This small winter rain, locally called 'mahawat', is very useful for rabi crops, especially wheat. A is wrong because the south-west monsoon brings rain from June to September, not in winter. B is wrong because the north-east monsoon gives winter rain mainly to the Tamil Nadu coast, not to the north-west. D is wrong because the retreating monsoon of October and November mostly affects the east coast and the south, and brings cyclones in the Bay of Bengal. Exam tip: winter rain in the north-west comes from western disturbances from the Mediterranean; winter rain in Tamil Nadu comes from the north-east monsoon.

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.

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.
