Why aren’t rivers/estuaries/lakes etc salty like the sea ?
In: Planetary Science
Rivers and lakes are fed from rainwater running from high ground to the sea. While rainwater does mostly come from the sea, it has to evaporate first. Evaporated water can’t carry salt, so it gets left behind in the ocean.
If you put a bunch of salt in a pan or water and boil it dry, you’ll see all the salt deposited on the bottom of the pan.
