Salvador Barron · Answer 1

B. distance of the deposit from the source.

Explanation:

The grain size of sedimentary deposit can indicate the distance of the deposit from the source. This is because, when sediment is transported by water, the sediment becomes victim of abrasion. As abrasion occurs, the edges of the grains of deposit are reduced, eventually leading to a rounder shape. However, this process can vary based on the distance of the deposit, the method of transportation and the energy characteristics of the transportation medium.
