Why is the ocean salty?
I wonder why lakes aren't salty?It's clear why rivers and lakes that eventually empty into the ocean are fresh. Rainwater washes the salt downstream to its ultimate destination.But many lakes do not have an outlet that leads to the sea. Water flows in and evaporates. Where does the salt go in that case?Or is it possible that the article doesn't tell the full story, and that salty rocks are confined to a limited number of areas?
