Sedimentary rock can be formed from lithified sediments.
Chemical sedimentary rocks, such as limestone and chert, are not classified by the size of clastic sediment that forms them, as they are formed from dissolved minerals that precipitate out of water. These rocks are made up of minerals that have been dissolved in water and then later crystallize out of solution.
A newly formed rock can break down into sediment through the process of weathering and erosion. Weathering involves the physical or chemical breakdown of rock into smaller pieces, while erosion transports these particles to new locations, where they can accumulate and eventually become sediment.
The rock formed from sediment that has been pressed together is called sedimentary rock. This type of rock is often formed from the accumulation and compression of sediments such as sand, silt, and clay over time.
sedimentary
Igneous rock undergoes weathering, where it is broken down into smaller particles by physical, chemical, or biological processes. These particles are then transported and deposited in layers by wind, water, or ice to form sediment. Over time, the sediment is compacted and cemented together to form sedimentary rock.

A sedimentary rock is formed.
Sediment
sedimentary
Igneous rock: Formed from the cooling and solidification of magma or lava. Sedimentary rock: Formed from the accumulation and compression of sediment. Metamorphic rock: Formed from the alteration of existing rock due to high heat, pressure, or chemical processes.
Igneous rock becomes sediment due to exposure to chemical and mechanical weathering at or near the surface.
