Some of it evaporates, returning to the atmosphere; some seeps into the ground as soil moisture or groundwater; and some runs off into rivers and streams. Almost all of the water ... WebAs the saltwater starts to evaporate, it leaves a salty layer on the sides of the glass. This layer stays moist, and that leaves a bigger area for the water to evaporate from. So that speeds up the process, even though the evaporation from the main surface is slower for the saltwater. We're not sure that's right, but it does make sense. Mike W.
