Final answer:
The longer sediment is transported before becoming a sedimentary rock, the smaller and more rounded the particles become, and the better sorted they are.
Step-by-step explanation:
The longer sediment has been transported before it is deposited and lithified into a sedimentary rock, the smaller the sediment particles become, the more rounded the sediment particles become, and the better the sorting of the sediment particles becomes. As sediment is transported over a long distance, it undergoes abrasion and sorting processes. During abrasion, the rough edges of the sediment particles are worn down, resulting in smaller and more rounded particles.
The sorting process separates particles based on their size, with smaller particles settling out first and larger particles settling out later.
