That's my science question too what class are you in
There are rocks which are known as weathered alteration rocks. But generally weathering leads to erosion. This eroded rock is called sediment, which can eventually form into sedimentary rocks.
Either a hills or a mature (well eroded, old) mountain range.
hydrates
That is correct. A detrital (or "clastic") sedimentary rock is formed by sediment grains that have been weathered and eroded by existing rocks and then deposited as layers.
topsoil?

Sedimentary rocks can be made from any kind of material, from other rocks to shells to plant material. Basically, any rock, from metamorphic to igneous and even to sedimentary, can be weathered and eroded. These particles and grains can be carried great distances by wind, water, ice, etc. before they are deposited and lithified (cemented) back together to form sedimentary 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.
