Rock does not melt in calderas. It melts in the upper mantle.
magma i believe
The crust is the outermost layer of the earth
It is called a destructive plate boundry...one type of crust is oceanic and the other is continental. when they meet the oceanic crust gets pushed down as it is heavier. the friction caused when it sinks creates huge earthquakes and the crust re-melts and gets forced upwards due to pressure to form a volcano.
Intrusive
The heavier (usually older and cooler hence more dense) oceanic crust normally subducts (is forced under) the younger less dense crust.
magma i believe
area between the mantle and the core where hot rock is forced into the crust
This is called a subduction zone.
The crust is the outermost layer of the earth
a sentence for crust
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
I ate all the pizza including(except) the crust.
In a subduction zone the crust is forced inot the mantle where it is eventually melted and destroyed
Earth's crust constitutes only a little portion of its entire volume.He doesn't eat pizza crust.

The contiental cdrust is forced under the continental crust in a process called subduction.
