Why is the ocean salty?

Answer 1

Because many minerals dissolve in water.

You might ask why the Great Lakes are not salty. Well, if they were the salts would, over time, flow to the ocean. And the new water feeding the great lakes (from rain and snow) would be salt free and hence the salt levels would fall over time.

There is no real way for the dissolved minerals in the ocean to go anywhere.

Answer 2

At the start, the ocean was clear water. But rock contains salt, and rivers flowing across the rocks dissolved it and brought it to the ocean. Since the salt never leaves the ocean, it got saltier and saltier until it reached the present level.

This isn't the whole story. The oceans reached the present level of saltiness over a billion years ago, and for some reason have never got any saltier since. I don't know why.

Answer 3

Simple. As wather flows in the rivers it picks up a small amounts of mineral salts from the rocks and soil of the river beds. This very-slightly wather flows into the oceans and seas. The wather in the oceans only leaves by evaporation (and the freezing of the polar ice) but the salt remains dissolved in the ocean-it does not evaporate. So the remaining wather gets saltier and saltier as time pas.

Answer 4

When rain falls on the land and runs down to the sea, minerals dissolve in the water and accumulate in the seas and oceans. The water then evaporates to continue the cycle and these minerals are left behind in the seas and oceans.

Answer 5

Its salty because when god made the Earth he said " Fish and other ocean creatures need a nice place to live... how about salt water?" and then there was salt water.

Answer 6

because of the sand ..
