Question:
We have several questions which relate to oceans. 1) Why can't humans drink salt water? 2) Why are the oceans made of salt water? 3) Do all the oceans contain the same level of salt water?



Replies:
Humans can't drink salt water because the kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking salt water, you have to urinate more water than you drank, so you die of dehydration. All parts of all oceans are not the same, a lot of this because of fresh water runoff from streams.
