Why are salt deposits found around playa lakes?
Answer and explanation
Correct answer: Because temporary water evaporates and leaves dissolved minerals
A playa is a shallow, usually temporary lake occupying a closed depression in an arid or semi-arid basin. Water entering the basin has no external outlet, so intense evaporation removes the water but leaves dissolved salts and other minerals behind. Repeated wetting and drying can build a salt crust around the basin. Sea waves, glacial ice, and river pothole erosion do not cause this concentration, so B is correct.
