Question

Assertion (A): Intrusive rocks have bigger grains.

Reason (R): They are formed outside, on the earth’s surface.

विकल्प

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

A is true and R is false.

Explanation:

Intrusive rocks cool slowly inside the Earth, so they form large grains this makes the assertion true.

The reason is false because intrusive rocks do not form on the Earth’s surface; that is where extrusive rocks form.
