Where do metamorphism rocks form?

where do metamorphic rocks form, the mantle crust or core?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. this is how they are formed.


What materials form Metamorphic Rocks?

Metamorphic rocks are formed from materials of pre-existing rocks of any form due to mainly increase in temperature, pressure and stress.

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.


What do rocks do under heat and pressure?

rocks can change form. There are three main types of rocks, sedimentary, Metamorphic and igneous. igneous. sedimentary rocks are rocks formed from sediment. Metamorphic rocks are rocks formed from heat and pressure. If other rocks are put under heat and pressure then they have a chance to change into metamorphic.
