All the classes of rocks. The igneous, sedimentary and metamorphic rocks
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.
The process by which rocks are formed is called the rock cycle. This cycle involves the formation, weathering, erosion, deposition, and compaction of rocks over time through various geological processes.
Artificial rocks, such as concrete or bricks, are not formed by the natural rock cycle. These rocks are man-made through processes like mixing cement, shaping, and hardening. They do not undergo the typical geological processes like weathering, erosion, and lithification that form natural rocks.
Sediment
Sedimentary rock.
Metamorphic rocks are formed from sedimentary rocks.
The rock cycle classifies rocks into three main categories: igneous rocks, formed from the solidification of molten rock; sedimentary rocks, formed from the compaction and cementation of sediments; and metamorphic rocks, formed from the alteration of existing rocks through heat and pressure.
