The Tropic of Cancer does not pass through which one of the following States?

  1. A.Manipur
  2. B.West Bengal
  3. C.Gujarat
  4. D.Jharkhand

Correct answer

A. Manipur

Explanation

The correct answer is A, Manipur. The Tropic of Cancer (23.5°N) passes through eight Indian states, and Manipur is not one of them; it lies just to the north.

From west to east the Tropic of Cancer crosses Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. It divides India roughly into two halves, with the northern part in the temperate zone and the southern part in the tropics. Manipur's southern border is at about 23.8°N, so the line runs through Mizoram, to its south, instead.

B is wrong because the line crosses West Bengal, passing near Krishnanagar in Nadia district.

C is wrong because Gujarat is the first state it enters from the west, in the Kutch region.

D is wrong because the line crosses Jharkhand, passing close to Ranchi.

Exam tip: Tropic of Cancer states, west to east: Gujarat, Rajasthan, MP, Chhattisgarh, Jharkhand, West Bengal, Tripura, Mizoram.

Statement I : Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.

Statement II : The Earth rotates from west to east.

  1. A.Both the statements are individually true and Statement II is the correct explanation of Statement I
  2. B.Both the statements are individually true but Statement II is not the correct explanation of Statement I
  3. C.Statement I is true but Statement II is false
  4. D.Statement I is false but Statement II is true
Show answer
Correct answer: B. Both the statements are individually true but Statement II is not the correct explanation of Statement I

Both statements are true, but the direction in which the Earth spins does not explain why tides occur. Tides are caused mainly by the Moon's pull, with the Sun adding a smaller pull; the Moon's tide-raising force is roughly twice the Sun's because it is so much closer.
