Explanation:
Weathering is the phenomenon in which surface of rocks are broken down and leaches or washed away.
The factors that affect the rock type and rate of weathering of said rock include:
- Composition: this translates to the <u>mineral composition </u>in the rock and how susceptible to chemical weathering reaction
- Surface area and porosity: Surface <u>porosity </u>determines how easily the rock can be leached by wind or rain.
- Climate: Mechanical weathering due to extreme climate change can cause freezing and thawing of the rocks, thereby enhancing disintegration of the rock. This is determined by the <u>ease of dissolving </u>of the rock.
