Additional information ❤
In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic.
Sedimentary and igneous rocks began as something other than rock.
Sedimentary rocks were originally sediments, which were compacted under high pressure.
Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened.
A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock.
Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.
