Question

1. How does composition of rock affect mechanical
weathering?​

Answer 1

Explanation:

The composition of rocks and climate also affect rates of weathering. The rate at which a rock weathers is affected by the amount of the rock's surface that is exposed to chemical weathering processes. As shown below, when a rock is broken into smaller pieces by mechanical weathering, more of its surfaces are exposed.
