Question

The densest layer of the earth is:

• A. Crust
• B. Outer Core
• C. Mantle
• D. Inner Core

Answer 1

Answer:

D. Inner Core

The Inner Core is the densest layer of the Earth.

It is primarily composed of iron and nickel and has a density of around 12.8 to 13.1 grams per cubic centimeter, which makes it much denser than the other layers of the Earth. The Inner Core is solid due to the immense pressure, despite the extremely high temperatures, which can reach up to 5,500°C (9,932°F).

This dense, metallic inner layer is surrounded by the Outer Core, which is liquid, and beneath the mantle.
