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

Correct answer

D. 1, 2 and 3

Explanation

The correct answer is 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. Day length also depends on latitude: at the equator day and night stay close to twelve hours all year, while towards the poles the gap between the longest and shortest day keeps widening, until beyond the Arctic and Antarctic Circles there are days of continuous light or darkness. Indira Point, the southern tip of Great Nicobar Island, lies at about 6°45' N and is the southernmost point of India.

Option A is wrong because it leaves out statement 3, which is true. Option B is wrong because it leaves out statement 2. Option C is wrong because it leaves out statement 1.

Exam tip: India's mainland spans about 8°4' N to 37°6' N; Indira Point at 6°45' N is the southernmost point.

  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.
