why is the sea salty ?

Answer 1

It is because of all the minerals dissolved and very small washed into it, from rivers, that have erode on the land.

It is a certain mix of minerals that makes it salty, but the dead sea is an example of where mineral are washed in, but dont run out to anywhere is, so it just gets saltier.

Answer 2

Because a) Salt readily dissolves in water and b) there is a lot of it present on the earth's surface.

All rain water that falls on land and doesn't evaporate eventually ends up in the sea, or in endorheic lakes. Therefore most salt present on the soil's surface has been washed into the sea and endorheic lakes over the millenia. When the water re-evaporates from those bodies the salt is left behind.

Answer 3

Because over the millions of years the water in the rain and rivers have dissolved the salt in the earth and taken it into the sea but as the water in the sea had evaporated the salt is left behind. The sea is very slowly getting saltier

Answer 4

Rivers dissolve salt as they flow towards the sea, and deposit it into the sea. Other processes can remove salt, but the net effect is the sea gets saltier.
Interestingly, given current rates of increase in salt, it would not take billions of yearsfor completely saltless water to become as salty as the sea is now.
This method of dating the earth was proposed by Newton's colleague Halley (as in the comet).
Just one of many evidences that the world is not billions of years old.
(The same argument holds for dozens of other minerals too.)

Answer 5

The sea is full of all atoms & particles that dissolve in water, but mostly H2O.
The most common on Earth are Na+ and Cl- which form salt. But all other dissolvable matters are also contained in the oceans, so don't drink from it - you never know, someone may have wee'd in it.

Answer 6

here we go.

rain falls on the land disolving minerals and 'stuff' and ends up in rivers rivers flow to the sea carrying the minerals (salt) into the sea

water gets evaporated and the cycle is repeated until now the amount of minerals in the sea make it salty

Hurray!

Why is the dead sea saltier its smaller and in a hot location

Answer 7

The number of male fish out number the female 100-1 ( poor fellas )

Answer 8

My 5-year-old has a book that purports to answer such questions. The answer it gives to the question is "because it contains salt" (seriously). I certainly feel much the wiser!
