The document discusses why the sea is salty. It notes that while all water contains some salt, rainwater does not. Rivers flow into the sea but the sea remains salty because of natural evaporation processes over long periods of time that have concentrated the salt in the oceans. The cycling of water between fresh sources like rivers and the salty sea is an ongoing process that has made the oceans much saltier than other bodies of water on the planet.
