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.
What else can I help you with?
What are the 2 things to form a metamorphic rock?
It is formed by the action of heat or pressure.
Which type of rock forms when exteme heat and pressure is applied?
Heat and pressure causes Metamorphic Rocks to form.
Why do metamorphic rocks often form deep under the surface of the earth?
Metamorphic rocks form deep under the Earth's surface because the high pressures and temperatures required for the transformation of existing rocks into metamorphic rocks are typically found at greater depths. These conditions are usually created by tectonic forces or by the burial of rocks under layers of sediment.
What is a protolith?
A metamorphic rock changes from one form to another by intense heat or pressue. The parent rock, or protolith, is the rock that undergoes change. It can be any rock type, sedimentary, igneous, and even metamorphic.
How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous rocks can form metamorphic rocks by being subjected to high heat and pressure, causing recrystallization of minerals. Igneous rocks can also weather and erode to form sediment, which can then be deposited, compacted, and cemented to form sedimentary rocks.
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.
What are the 2 things to form a metamorphic rock?
It is formed by the action of heat or pressure.
Which rock form heat and pressure?
Metamorphic rocks form from heat and pressure.
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 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
Rocks that are changed by heat and pressure will form?
Metamorphic Rock
Do heat and pressure form metamorphic rocks?
yes it does :p
What rocks form under heat and pressure?
Metamorphic Rock
