Which of the following lakes was formed as a result of tectonic activity?

  1. A.Chilika Lake
  2. B.Wular Lake
  3. C.Kolleru Lake
  4. D.Sambhar Lake

Correct answer

B. Wular Lake

Explanation

The correct answer is B, Wular Lake. NCERT's geography textbook describes Wular Lake in Jammu and Kashmir as a lake formed as a result of tectonic activity, that is, by movements of the Earth's crust. It lies in the Kashmir Valley in Bandipora district, and the Jhelum river flows into it and out of it, so the lake soaks up the river's floodwater. Wular is the largest freshwater lake in India and has been a Ramsar wetland since 1990. Its area changes a lot with the seasons, roughly from 30 to 260 square kilometres. Option A is wrong because Chilika in Odisha is a lagoon, a coastal lake cut off from the sea by a sand bar. Option C is wrong because Kolleru in Andhra Pradesh is a shallow lake lying between the deltas of the Godavari and the Krishna. Option D is wrong because Sambhar in Rajasthan is an inland salt lake of the dry region, fed by seasonal streams and known for salt production. Exam tip: Wular = largest freshwater lake and tectonic; Chilika = largest lagoon; Sambhar = largest inland salt lake.

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.

  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.
