Sedimentary rock is formed in layers which were laid down one by one on top of another. Some of the layers are thin, some are thick. Layers are made by deposition of sediment, organic matter, and chemical precipitates. Of the rocks exposed on the Earth's surface, 66 percent of it are sedimentary rocks. Deposition is followed by squeezing of ...

Sedimentary rock can also be formed when the shells of sea creatures fall to the floor of the sea after the creatures die. When the shells form a thick enough layer they become compressed and form rock. In some places where there are shallow bodies of water another kind of sedimentary rock may be formed. In these cases, if the surrounding air ...
