Define metamorphic rock
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form
What is the cycle that mentions metamorphic rocks, sedimentary rocks, and ingenious rocks?
The Rock Cycle.
What is the softest rock in the rock cycle?
sedimentary.
Igneous rocks are formed through the cooling and solidification of magma or lava.
The two main kinds of igneous rocks are intrusive igneous rocks, which form from magma that cools below the Earth's surface, and extrusive igneous rocks, which form from lava that cools on the Earth's surface.
