1. summarize what

is the result of a rock
undergoing mechanical
weathering?

Explanation:

Mechanical weathering (also known as physical weathering) involves processes like freezing - thawing, abrasion, etc., that break rocks into smaller pieces. The key point is that the chemical composition of the rock remains unchanged; only the size and shape of the rock fragments are altered. So the result is that the rock is broken down into smaller pieces (sediments or rock fragments) without changing its chemical composition.

Answer:

When a rock undergoes mechanical weathering, it is broken down into smaller pieces (such as sediments or rock fragments). The chemical composition of the rock remains unchanged; only the physical size and shape of the rock are altered.
