Chemical decomposition

Answer 1

The mechanism of weathering that smooths rocks in a stream through water action is most likely:

A. Abrasion

Abrasion occurs when rocks and sediment are worn away due to contact and friction with other materials, typically facilitated by water movement, which can smooth and polish the surfaces of the rocks over time.
