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
rocks that are made up of sediments cemented together
Sedimentary rocks.

No, rocks made of sediments are called sedimentary rocks. Igneous rock comes from volcanic activity -- lava and the like.

The breaking up of rocks into sediments is called weathering. Weathering can be physical (mechanical) or chemical in nature, and it is a key process in the formation of sedimentary rocks.
Sedimentary rocks are made up of materials that were once part of another rock. Most sediments are deposited on ocean floors or at the bottom of rivers and lakes.Clastic sedimentary rocks form from layers of sediments. Pressure causes the water around the sediments to be squeezed out and the sediments are cemented together.
Ocean water breaks rocks into sediments
Ocean water breaks rocks into sediments
From rocks in rivers and lakes and when the rocks break up over time the sediments inside the rocks go into the rivers and lakes and overtime into the water supply.
