Why is the water in oceans salty?

Answer 1

It is because when the rivers pour water in seas they carry some minerals along with them which contains mostly NaCl(Common Salt) which gives a salty taste to the oceans water. One more reason for it is that the sea bed contains silt which also has Common Salt contained in it.
