Explain how the texture of a rock surface affects how fast it physically weathers by water. 3-5 SENTENCE

Answer 1

The texture of a rock surface significantly influences its rate of physical weathering by water due to the presence of fine or coarse features. Rough and textured surfaces provide more area for water to interact with the rock, leading to increased mechanical breakdown as water can more easily seep into crevices and expand when it freezes. Conversely, smooth surfaces limit the contact area and thus slow down the weathering process, as water tends to flow over them rather than infiltrate. This interaction, along with variations in porosity and permeability, determines how effectively water can penetrate and contribute to the physical weathering of the rock.
