Question

Assertion (A): The outer core is in solid state while the inner core is in liquid state.

Reason (R): The inner core records a temperature of 5,000°C.

Options

• 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 false and R is true.

Explanation:

The outer core is in a molten (liquid) state due to very high temperature, while the inner core is in a solid state because the extremely high pressure there compresses it into solid. The inner core does have a temperature of about 5,000°C, but this heat is not enough to keep it liquid because pressure dominates. Hence, the assertion is false and the reason is true.
