Does rate of chemical weathering increase or stay same when a rock & what happens to rate of physical weathering as rate of chemical weathering increases?
Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more places for chemical weathering to occur. Rocks at the peak of a mountain weather faster because they are exposed to more ice, rain, and wind. 7. When a rock is mechanically weathered, the surface area of the rock can increase. Therefore, more of the rock is exposed to chemical weathering, and the rate of chemical weathering increases.Physical weathering speeds up the process of chemical weathering because it exposes more surface area for chemical reactions to take place. Physical weathering is the process of breaking down rock without causing any change in chemical composition.
