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

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

Explanation:

Magma is a molten or partially molten rock form. Magma consists of silicate liquid, although carbonate and sulfide melts occur as well. It moves either to depth or to Earth’s surface and is ejected as lava. Suspended crystals and fragments of un-melted rock get transported in the magma dissolved volatiles may separate as bubbles and some liquid get crystallize during movement.

Several interrelated physical properties determine the characteristics of magma, including chemical composition, viscosity, dissolved gases, and temperature.Magma also form igneous rock.

Therefore the magma is heated and becomes less dense by the core moving it toward the crust.
