Answer:
The correct answer is a) Weathering.
Explanation:
Weathering refers to the process of separating minerals, rocks, or other compounds through contact with the atmosphere or water, which is why it is divided into chemical and physical weathering.
For example, in the case of floodwater hitting against the canyon wall, it is known as a physical weathering, since hitting the water in the canyon produces a break in the rocks, this does not affect the chemical composition of the rocks alone its physical structure since the rock is breaking into smaller pieces by the blow of the water.
