Sedimentary Rock. Sedimentary rocks are formed when weathered (broken down) pieces of sediment (fragments of minerals, rock, and organic material) are carried by moving water into a larger body of water like a lake or the ocean.

Interactives . The The Rock Cycle . Types of Rocks

Types of Rocks Rocks are not all the same! The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material.

sedimentary rocks processes and environments

SEDIMENTARY ROCKS There are two groups of sedimentary rocks. One group is the clastic or detrital sedimentary rocks. These are rocks composed primarily of fragments (i.e. clasts, or detritus) of pre-existing rocks. They are formed by the processes described above. A second group are the chemical and biochemical sedimentary rocks.

Many sedimentary rocks are made from the broken bits of other rocks. These are called clastic sedimentary rocks. The broken bits of rocks are called sediment. Sediment is the sand you find at the beach, the mud in a lake bottom, the pebbles in a river, and even the dust on furniture. The sediment may, in time, form a rock if the little pieces ...
