Question

In the Earth’s Mantle, what material is moving constantly building up pressure?

A Iron, Nickle
B Magma
C Ice and Fire
D Salt water

Answer 1

B. Magma

Step-by-step explanation:

C and D are automatically out.

It is not A because Iron and Nickel are in the Earth's core.

So that leaves you with magma, and that's how volcanoes erupt because of the pressure the magma is under.
