Why the sea is salty
Did you know that seventy percent of the earth is covered in water and thirty percent is land? Well all over the world, most of the water is salty.
When it rain, water flows through soil into the rocks. We all know that rocks contain chemicals. Salt is one of them. Then the salty water flows through the river and into the sea.
On an extremely hot day water evaporates. Only water evaporates. This is what forms clouds.
Over millions and millions years, salty water has been flowing from the rivers into the sea. Hence the sea is very salty. This cycle continues on and on.
