Which risk increases following increased freeze-thaw cycles on granite?

💡 Explanation

Increased freeze-thaw cycles accelerate physical and chemical weathering, increasing the available surface area for chemical reactions involving water via the mechanism of frost wedging, because cracks form as water expands and contracts, rather than solely mechanical weathering; therefore dissolution increases but biological soil crusts and the other options would take far longer to manifest.
