Answer:
When mechanical weathering breaks a large rock into smaller pieces, the total surface area of the rock increases.
Explanation:
- The disintegration of 'rock into smaller pieces' is known as mechanical weathering. It increases the rate of chemical weathering.
- This is caused by pressure release, plant growth, ice wedging. This makes the rock to split apart as a result of the 'cracks and pores' in the rocks. Plant acids too help to dissolve the rocks.
