Where do the sediments that make up sedimentary rocks come from?
Sediments are the result of weathering which breaks up pre-existing rocks. There are two types of weathering; Mechanical and Chemical. After the rocks are weathered and broken down into sediments they are transported via water, wind, glaciers, or gravity to different depositional environments. Finally after being deposited the sediments accumulate to form a sedimentary rock through lithification. Sediments come in all different shapes, sizes, and sortings. The way sediments are sized, shaped, and sorted can tell us about their depositional environment and how they journeyed to get there. What’s the difference between Clastic, Chemical and Biochemical sedimentary rocks? Clastic or detrital sedimentary rocks are made of sediments that are the result of weathering and transport. Chemical rocks are created from chemical precipitation. Biochemical or organic rocks are made up biological remains. What are properties of Sedimentary rocks used to identify them? Properties of sedimentary rocks
