Question

Which processes relate to mechanical weathering? Check all that apply.

Answer 1

Answer:

Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. ... That process occurs when the water inside of rocks freezes and expands. That expansion cracks the rocks from the inside and eventually breaks them apart.

Answer 2

Answer:

Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
