Question

Assertion (A): Core is also called NIFE.

Reason (R): Core is made up of nickel and iron and has got the maximum density.

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

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

Explanation:

The core is called NIFE because it is mainly made up of Nickel (Ni) and Iron (Fe). It is the densest layer of the earth due to the presence of these heavy metals, which explains its maximum density compared to other layers. Thus, both the assertion and reason are true, and the reason correctly explains the assertion.
