Why is seawater salty, when water from the lake isn’t?
In: Earth Science
Rivers erode the land they run over, picking up minerals (such as salt) as they go. Most lakes aren’t the ultimate stopping point for this water, just a layover. The minerals in the water get carried on as the lakes drain into further rivers, and ultimately, to the ocean. There are a few exceptions: the Dead Sea, in Israel/Jordan, and the Great Salt Lake, in Utah, come to mind. In these oceans and the couple of lakes with no outlet, these minerals build up over millions of years, consentrating as the water evaporates but the solute stays
