Final answer:
Climate, chemical composition, and size of mineral grains affect the rate of rock weathering.
Step-by-step explanation:
The rate at which rocks weather can be influenced by several factors. Climate plays a role in weathering, as temperature, moisture, and wind can cause different patterns of weathering. The chemical composition of the rock can also affect how quickly it weathers, with some rocks being more resistant to weathering than others. Additionally, the size of mineral grains in the rock can impact the rate of weathering, with rocks with larger mineral grains weathering faster.
Surface area does impact the rate of rock weathering, contrary to the statement provided. Increased surface area exposes more of the rock to weathering agents, which can speed up the weathering process.
