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.

There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.

Clastic rocks are made from fragments of pre-existing rocks.

Igneous rocks.
Rocks that form as a result of cooling magma?
Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
Can metamorphic rocks form form other metamorphic rocks?
yes, all rocks can form from all others depending on pressure, etc
What rocks form from the sediments of the other rocks?
Sedimentary rocks.
When molten rocks cools what rocks form?
