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.
Sedimentary rocks are ones formed by solidified mud and loose earth. Metamorphic rocks are ones formed by some sort of change, such as melting and re-cooling. So they are similar in some senses (they are both rocks, both of the earth) but in others they are very different (physical properties).
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
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
Sedimentary rocks are usually formed in water, but not always. Some sandstones, for example, form in deserts.

Sedimentary rocks form as a direct result of the deposition of material on the surface of the Earth. They may also form in bodies of water.

Sedimentary rocks are formed when eroded earth builds up
