Question

During sedimentation, materials are often sorted by ________?

1) shape
2) color
3) porosity
4) size
5) atomic weight

Answer 1

During sedimentation, materials are often sorted by size. The size of grains within sedimentary rocks can tell us a lot about the transport and depositional history of the sediment.

Step-by-step explanation:

During sedimentation, materials are often sorted by size. The size of grains within sedimentary rocks can tell us a lot about the transport and depositional history of the sediment. Well-sorted sedimentary rocks have grains that are about the same size, indicating that the sediment has traveled a far distance from its source. Geologists use various methods, such as grain size analysis and ternary plots, to classify and describe sediment based on its size.
