In contact metamorphism - a nearby magma melt.
In regional metamorphism - the geothermal gradient from the mantle/core
In mylonites, the heat of friction across the fault plane.
In astroblemes, the kinetic energy of the impactor.
--------------------------------
The origin of the heat that creates metamorphic rock can be from friction caused by colliding plates, but by far the vast majority of the heat has originated in Earth's interior, caused by radioactive decay, remnant heat from Earth's formation, and pressure.

Which type of rock forms when exteme heat and pressure is applied?
Heat and pressure causes Metamorphic Rocks to form.
Which process can cause metamorphic rock to change into igneous rock?
Melting of the bulk of the metamorphic rock, then solidification from cooling, will form an igneous rock.
What 2 things are needed to change a rock into metamorphic rock?
intense heat and pressure.
Why do metamorphic rocks often form deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
What are two agents of metamorphism?
Heat, Pressure, and Chemically active fluids.
What is needed for any kind of rock to become metamorphic?
Heat, for sure, and most often a combination of heat and pressure is needed for metamorphic rock creation.
Which rock form heat and pressure?
Metamorphic rocks form from heat and pressure.
Which type of rock forms when exteme heat and pressure is applied?
Heat and pressure causes Metamorphic Rocks to form.
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
What form from heat and pressure?
Metamorphic rock
What are the steps needed to form metamorphic rock from magma?
Metamorphic rock is not formed directly from magma. Igneous rock is formed from the solidification of magma and lava.
Which process can cause metamorphic rock to change into igneous rock?
Melting of the bulk of the metamorphic rock, then solidification from cooling, will form an igneous rock.
What has to increase for metamorphic rocks to form?
Heat and pressure.
What has to increase for metamorphic rock to occur?
You need to increase heat and / or pressure for a metamorphic rock to form.
What provides the heat that drives the formation of igneous and metamorphic rock?
Earths hot interior
What provides the heat that drives the formation of igneous and metamorphic rocks?
Earths hot interior
What makes a metamorphic rock unique?
Metamorphic Rocks are rocks that have changed form due to heat and pressure.
