Which of the statement(s) given above is/are correct?

• A.
  1 only
• B.
  2 only
• C.
  Both 1 and 2
• D.
  Neither 1 nor 2

Answer 1

The correct option is B

2 only

Explanation:

Statement 1 is incorrect: Where the coasts are mountainous, such as the Rocky Mountain and the Andean coasts, the continental shelf may be entirely absent or very small. These mountains are the result of plate’s subduction.

Statement 2 is correct: The continental shelf is the stretched margin of all continents into the ocean. It is the shallowest part of the ocean. The shallowness of continental shelves enables sunlight to penetrate through the water, which encourages plankton growth. These areas also get nutrients from the land. They are also the richest fishing grounds in the world.
