If the temperature of rock rises above the melting point of the mineral the rock is composed of what?

Magma can form when the temperature of rock rises above the melting point of the minerals the rock is made of; when excess pressure is removed from rock that is above its melting point; and the addition of fluids, such as water, may decrease the melting point of some minerals in the rock and cause the rock to melt.

Magma

Hope this helps!

since there isn't any suggested answers i will give you the reason and hopefully you can figure it
