Question

This image shows how magma moves through the Earth’s mantle.



Which describes why the magma moves in the direction of the arrows?

The magma is cooled and becomes more dense by the core moving it toward the crust.
The magma is heated and becomes more dense by the core moving it toward the crust.
The magma is cooled and becomes less dense by the core moving it toward the crust.
The magma is heated and becomes less dense by the core moving it toward the crust.

Answer 1

The magma is heated and becomes less dense by the core, causing it to rise toward the crust. Heating lowers the magma's density so it moves upward (convection).
