They make rocks more brittle and prone to erosion.

Explanation: Droughts reduce moisture and vegetation cover, increasing thermal stress, cracking, and wind erosion of rock and soil. The other choices are incorrect: droughts don’t create igneous cover, cementation requires water and minerals (so is less likely), and while drying lakes can expose buried layers, the general effect of more frequent droughts is increased brittleness and erosion.
