All the classes of rocks. The igneous, sedimentary and metamorphic rocks
Some extraterrestrial rocks were not formed via the terrestrial rock cycle.
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
it is formed by broken down rocks
The rock cycle describes how rocks are formed, and how they change to sedimentary rock, to metamorphic rock, to magma, to igneous rock, to sediment, and back to sedimentary rock.
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.

Metamorphic rocks are formed from sedimentary rocks.
The rock cycle is the best way to learn about how rocks are formed.
