Question
Explain how the texture of a rock surface affects how fast it physically weathers by water.(4 points)
The texture of a rock surface can affect how fast it physically weathers by water in several ways. First, rocks with a smoother texture tend to have less surface area exposed to water, which can slow down the weathering process. On the other hand, rocks with a rough or porous texture have more surface area exposed to water, allowing for more interaction and faster weathering. Additionally, the presence of cracks or fractures in a rock can allow water to penetrate deeper into the rock, leading to more rapid weathering through processes like frost wedging. Overall, the texture of a rock surface plays a significant role in determining how fast it physically weathers by water.
