❓ why
Why do some lake shores have salt crusts instead of beaches?
Quick Answer
Salt crusts form when a lake’s water evaporates and leaves dissolved minerals behind on the shoreline.
The Full Story
In arid regions, lake water can rise and fall with the seasons. As the water evaporates, dissolved salts and minerals are deposited on the edges of the basin. Repeated wetting and drying can create thick white crusts or salt flats. These shores often form around saline or alkaline lakes with no outlet. The result is a bright, hard shoreline very different from a sandy beach.
Key Facts
1.Evaporation leaves minerals behind
2.Salt flats often form around closed-basin lakes
3.Dry climates favor crust formation
