yes
The opening in Earth's crust through which magma rises to the surface is known as the?

What is an area where magma melts through the crust in the middle of a plate?
A hot spot is an area where magma from deep within the mantle rises through the crust in the middle of a tectonic plate, creating volcanic activity and forming a chain of volcanic islands or seamounts. The Hawaiian Islands are a well-known example of hot spot activity.
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
What is the molten material under the earth's crust?
Magma
Why does magma in the mantle rise through the crust above it?
