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 are the 2 things to form a metamorphic rock?
It is formed by the action of heat or pressure.
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.
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 TWO THINGS ARE NEEDED TO FORM A METAMORPHIC ROCK?
To form a metamorphic rock, two key factors are needed: heat and pressure. These conditions alter the mineral composition and structure of pre-existing rocks (igneous, sedimentary, or even other metamorphic rocks) without melting them. Additionally, the presence of chemically active fluids can facilitate mineral changes during the metamorphic process.
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.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
Can heat form an igneous rock or a metamorphic rock?
metamorphic because it melts the rock and forms another
What makes a metamorphic rock unique?
Metamorphic Rocks are rocks that have changed form due to heat and pressure.
How does metamorphic form?
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
