Some examples of clastic sedimentary rocks include sandstone, conglomerate, shale, and breccia. These rocks are formed from the accumulation of fragments of pre-existing rocks and minerals, which are then compacted and cemented together over time.
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
Clastic sedimentary rocks are formed by the weathering, erosion, deposition, compaction and cementation of other rocks. Chemical sedimentary rocks however may be precipitated directly from saturated solutions (examples incldue the evaporitic rocks and certain types of carbonates such as oolitic limestones). Some other sedimentary rocks may be biogenic in origin (such as the linmestones that are formed of coral reefs).
Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
Not all rocks are, only sedimentary rocks are truly made up of sediments. Some metamorphic rocks do because they are formed when heat and pressure are applied to sedimentary rocks, which makes sediments the basis of these rocks as well
Sedimentary rocks are usually formed in water, but not always. Some sandstones, for example, form in deserts.
Extrusive igneous rocks, some sedimentary rocks
Extrusive igneous rocks and some sedimentary rocks are formed above ground.

Well, isn't that just fascinating? Sedimentary rocks formed from the remains of dead organisms are called biogenic sedimentary rocks. Some common examples include limestone, formed from the accumulation of marine animal shells, and coal, which comes from the remains of ancient plants. Nature has a beautiful way of preserving life in the rocks around us.
Sedimentary rocks are formed when eroded earth builds up

Are meatmorphic rocks and also perhaps soil.
