Answer 1

The correct answer is Mantle.

Key Points

The mantle:

The mantle extends up to a depth of 2900 km below the crust.
It separates the crust from the core.
The upper part of the mantle is known as the asthenosphere.
Nearly 84% of the earth’s volume and 67% of the earth’s mass is occupied by the mantle.
The major constituent elements of the mantle are Silicon and Magnesium and hence it is also termed as SIMA.

Additional InformationThe crust:

The crust is the uppermost layer over the earth’s surface.
It is the thinnest layer.
it is only about 5 km on the ocean floors, which mainly consists of silica and alumina thus called sial (si-silica and al-alumina), and 35 km on the continental masses, which mainly consists of silica and alumina.

The core:

The innermost layer is the core with a radius of about 3500 km and divided into Inner and Outer core.
It is called nife (ni – nickel and fe – ferrous – iron) as it's mainly made up of nickel and iron.
Central core is called the Inner core and has a very high temperature and pressure.
