Final answer:
Moisture among sediment grains can affect their characteristics and transport. Well-sorted and rounded grains indicate long-distance travel, while angular and poorly sorted grains imply a short distance from the source. Moisture also plays a role in the lithification process of turning sediment into sedimentary rock.
Step-by-step explanation:
Moisture among sediment grains can affect their characteristics and transport. When grains are well-sorted and rounded, it indicates that they have traveled a far distance. On the other hand, angular and poorly sorted grains suggest that they have not traveled a far distance and are close to their source. Moisture can also play a role in the lithification process, where compaction and cementation turn sediment into sedimentary rock.
