Hot local wind that flows over north India in summer is known as:

  1. A.Loo
  2. B.Chinook
  3. C.Mango showers
  4. D.Purga

Correct answer

A. Loo

Explanation

The correct answer is A, Loo. The Loo is the hot, dry, dusty wind that blows over the plains of north India in summer. It develops in May and June, usually from the west or north-west, and blows strongest in the afternoon, when temperatures can cross 45 degrees Celsius in Rajasthan, Punjab, Haryana, Delhi and Uttar Pradesh. Long exposure to it causes heat stroke, so schools and outdoor work stop in the afternoon during a Loo spell. It weakens once the monsoon reaches the plains. Option B is wrong because the Chinook is a warm, dry wind that descends the eastern slopes of the Rocky Mountains in North America and is nicknamed the snow-eater. Option C is wrong because mango showers are pre-monsoon rain in Kerala, Karnataka and Tamil Nadu that helps mangoes ripen, not a wind. Option D is wrong because Purga is a cold, snow-laden wind of the Siberian tundra. Exam tip: Loo is hot and Indian, Chinook is American and warm, Purga is Siberian and cold.

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.

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.
