Question

difference between clastic sediments and chemical sediments​

Answer 1

Explanation:

Chemical sedimentary rocks: Rocks which are formed due to chemical precipitation or any other chemical processes like evaporation, are called chemical sedimentary rocks. Like, any primary carbonate rocks like limestones or dolostones which are formed due to precipitation of calcium or magnesium carbonate from water.Another example of chemical sedimentary rocks are evaporites. Over saturated water mass with high amount of evaporation deposits large amount of NaCl (Halite) called evaporite. Anhydrites and gypsum are two more examples of evaporites.

Answer 2

Answer:

Clastic sedimentary rocks:

The word clastic came from “clasts” which means grains. So, sedimentary rocks with distinct grains (finer or larger) and deposited in a mechanical/physical process (like settling down of finer grains from a river water and then undergoing lithification) are called Clastic rocks. Mainly silicic rocks like sandstone, shale etc. fall under clastic rocks.
