Rivers are constantly running. They pick up minerals and salt from the rocks they pass by. Rivers run towards the ocean and when river water mixes with the ocean water, the salt mixes along with it.

How much salt is in a cup of ocean water?
Exercise 18.4 Salt Chuck
To understand how salty the sea is, start with 250 mL of water (1 cup). There is 35 g of salt in 1 L of seawater so in 250 mL (1/4 litre) there is 35/4 = 8.75 or ~9 g of salt. This is just short of 2 teaspoons, so it would be close enough to add 2 level teaspoons of salt to the cup of water.
