How does the increase in size of a rock affect the rate at which it weathers?

The increase in size of a rock generally decreases the rate at which it weathers, as larger rocks have a smaller surface area-to-volume ratio. This means there is less surface area exposed to weathering agents such as water, air, and biological organisms. Consequently, larger rocks take longer to break down compared to smaller rocks, which have more surface area exposed for weathering processes. However, other factors such as rock type, environmental conditions, and the presence of fractures can also significantly influence weathering rates.
