science question?..help please?!?

Question

Pure water evaporates continuously from the oceans while salts are left behind. Explain why the salinity of ocean water does not increase over time. Please cite specific examples from around the world.

HELP PLEASE.!

Answer 1

It does increase. The Dead Sea is a wonderful example of salinity increasing in because of evaporation.

Rivers will bring more salt into the ocean as if flows. The rain washes minerals into the rivers and then flows to the ocean. The river is not as salty as the ocean, but there is salt in it. Each year, more and more salt is added to the ocean.

Here is another site that discusses it better.

Answer 2

I read that the salinity of the oceans has been stable for eons.
Why, I forget, but it has to do with dispersion. In confined seas I suppose the saltiness would increase to the point that it could almost be solid, like the Dead Sea, the Salton Sea, The Great Salt Lake of Utah, and the largest of alll--the Aral Sea.

Answer 3

the Water and the Salt.
Fresh water continually enters the oceans. Every river in the world is fresh water, all going into the oceans.

Some salt in the oceans is taken up by organisms and used to make coral reefs, for metabolism, etc.

Answer 4

The water comes back as rain without salt. It either lands directly back into the ocean - or it hits land and flows back to the ocean through rivers.

Answer 5

i dunno any examples but rain falls in the ocean and fresh water rivers flow into the ocean so there is about the same amount evaporating as flowing into the ocean, unless the place is arid, such as the dead sea. All the water evaporated and none replaced it so it's a salt plain.

Answer 6

The water vapor condenses as rain, and eventually flows back to the ocean as rivers. Name as many rivers as you please.
