What happens when molten material is heated from Earth's core?

It sinks towards the core.

It rises up towards the crust.

Lava travels away from the core and forms the crust.

Lava travels away from the crust and forms the mantle

Option (2)

Explanation:

The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.

Thus, magma rises from the bottom of the mantle towards the crust.

Hence, the correct answer is option (2).

It rises up towards the crust.
