Final answer:
Clastic sedimentary rocks, such as the Tapeats Sandstone in the Grand Canyon, can be distinguished from biochemical sedimentary rocks based on their composition and origin.
Step-by-step explanation:
Clastic sedimentary rocks can be distinguished from biochemical sedimentary rocks based on their composition and origin.
Clastic sedimentary rocks such as the Tapeats Sandstone in the Grand Canyon are made up of fragments or clasts of geologic detritus, including minerals and rocks. These fragments are the result of mechanical weathering and erosion of pre-existing rocks. Examples of clastic sedimentary rocks include sandstone, shale, and conglomerate.
In contrast, biochemical sedimentary rocks are formed from the remains of living organisms or from chemical precipitation. Examples of biochemical sedimentary rocks include limestone, coal, and chalk.
By examining the composition and origin of a sedimentary rock, it is possible to determine whether it is clastic or biochemical.
