What deposit may remain after temporary desert lakes dry up?
Answer and explanation
Correct answer: Salt flat or playa deposit
The governing process is evaporation in an enclosed, arid basin. Temporary desert lakes receive dissolved salts and fine sediment, but intense heat removes the water faster than fresh water enters it. The salts and mud are therefore concentrated and left behind as a playa or salt flat, sometimes with crusts on the surface. Option C is correct; a U-shaped valley is glacial, a wave-cut platform is coastal, and a sea arch is formed by marine erosion.
