A metaporphic rock is formed when a rock is put under extreame heat and preasure for many (often thousands or millions) of years. This changes it into a new type of rock. This new rock is called a Metamorphic rock.

∙ 14y agoDifferent types of metamorphism include:
1. Thermal metamorphism: involving heat alone, without significant pressure effects. Normally associated with igneous intrusions, where contact metamorphism occurs.
2. Dynamic metamorphism: caused by intense local stresses which break up rocks, sometimes reducing them to a fine powder. This method produces mylonite.
3. Regional metamorphism: the large-scale action of both heat and pressure, producing a wide range of new mineral assemblages. Regional metamorphism is always associated with orogenies and igneous intrusions.
4. Retrograde metamorphism: any kind of metamorphism that produces rocks of a lower metamorphic grade from those of a higher grade.
5. Autometamorphism: this involves changes which occur during the cooling of an igneous mass, as a result of the activity of residual fluids within the mass.
1 and 3 are probably the most common and important.

What are the causes of the metamorphic rocks?
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 are metamorphosed the pressure causes them to become what?
Deformed, and change into metamorphic rocks.
Which types of rocks are not metamorphic rocks?
Sedimentary and Igneous rocks are not metamorphic rocks. Metamorphic rocks however are igneous or sedimentary rocks that have undertaken metamorphism (In extreme heat and/or pressure the minerals are forced to recrystalize) and become metamorphic rocks. If the heat/pressure causes the rock to melt into liquid rock than it is no longer metamorphi, it is igneous. Hope this helps :)
How does metamorphic rock turn to sedimentary rock?
Sedimentary rocks get turned in to metamorphic rocks by heat and pressure. They get heated by magma and convection currents, which causes the rock to change.
What causes sedimentary or igneous rocks to turn into metamorphic rock?
Heat and Pressure.
How does metaporhic rocks form?
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are.
What force causes sedimentary rocks to be transformed into metamorphic rocks?
Pressure and heat from being buried under mountains.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Are unakite rocks Sedimentary rocks Metamorphic rocks or Igneous rocks?
metamorphic
What is the difference of igneous rocks and metamorphic rocks?
lava and/or magma cools and forms igneous rocks. igneous rocks go through weather and erosion which forms sediments. these sediments are collected and compacted. this causes sedimentary rocks. the sedimentary rocks go through weather and erosion as well as being exposed to heat and pressure. this causes metamorphic rocks. metamorphic rocks go through heat and pressure and then they melt and become lava or magma again. this is called the rock cycle.
What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
