Respuesta :

Chemical sedimentary rocks form by chemical precipitation that begins when water traveling through rock dissolves some of the minerals. These minerals are carried away from their source and eventually redeposited, or precipitated, when the water evaporates away.
Answer: Minerals dissolve and crystallize. The remains of plants and animals.

Explanation: The chemical sedimentary rocks form when the parent material weathers into a sediment. The sediment includes chemical inorganic minerals and partially or completely degraded organic matter that comes from the remains of plants and animals. The layers of sediments get compacted with overlying heat and pressure which leads to the formation of chemical sedimentary rocks.
