Why Are Sedimentary Rocks Found in Layers?

Answer

Sedimentary rocks form where there has been water at one time. Minerals carried by wind, water, ice, or gravity are dropped off in bodies of water where they sink. They slowly make layers that build on top of each other. Pressure is put on lower layers until they harden into a rock. Erosion and weathering drop different things to the bottom of the water for each layer, thus the different colours or textures.
