Basically a bunch of rocks come together( are pressed together by heat and pressure) in a process called Lithification , those rocks can be either Sedimentary or Igneous rocks.

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.


Are metamorphic rocks naturally formed?

Metamorphic rocks are naturally formed. they are formed from natural changes that happen to other rocks.


Are metamorphic rocks only formed by igneous rocks?

No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.


What rocks are formed by the effect of heat and pressure on other rocks?

the metamorphic rocks are formed by heat and extreme pressure from other rocks


Can you describe the 4 rocks formed by metamorphic grade which are Slate Phyllite Schist and Gneiss?

Slate is a low-grade metamorphic rock characterized by fine-grained foliated structure. Phyllite is intermediate-grade metamorphic rock with a greater degree of crystallization and foliation than slate. Schist is a medium-grade metamorphic rock with visible mineral grains and strong foliation. Gneiss is a high-grade metamorphic rock with distinct banding of light and dark minerals and high crystallization.


When you look at a metamorphic rock how can you tell it is one?

Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.


What kind of rock does a metamorphic rock start as?

What can metamorphic rocks change into?

Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.

What metamorphic rocks are formed from mudstones?

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.
