Why is the seawater salty?

Answer 1

All water, even rain water, contains dissolved chemicals which scientists call "salts." But not all water tastes salty. Water is fresh or salty according to individual judgment, and in making this decision man is more convinced by his sense of taste than by a laboratory test. It is one's taste buds that accept one water and reject another.

SOURCES OF THE SALTS...
Sea water has been defined as a weak solution of almost everything. Ocean water is indeed a complex solution of mineral salts and of decayed biologic matter that results from the teeming life in the seas. Most of the ocean's salts were derived from gradual processes such the breaking up of the cooled igneous rocks of the Earth's crust by weathering and erosion, the wearing down of mountains, and the dissolving action of rains and streams which transported their mineral washings to the sea. Some of the ocean's salts have been dissolved from rocks and sediments below its floor. Other sources of salts include the solid and gaseous materials that escaped from the Earth's crust through volcanic vents or that originated in the atmosphere.


IF FRESH WATER FLOWS OUT TO THE SEA, WHY IS THE SEA STILL SALTY?...
The Mississippi, Amazon, and Yukon Rivers empty respectively into the Gulf of Mexico, the Atlantic Ocean, and the Pacific Ocean, all of which are salty. Why aren't the oceans as fresh as the river waters that empty into them? Because the saltiness of the ocean is the result of several natural influences and processes, the salt load of the streams entering the ocean is just one of these factors.

Answer 2

Sea water is a solution containing about 25 grms of salts (mainly Sodium Chloride) per one liter of pure water. Sodium chloride is salty and is our common table salt.

With the Water Cycle the salinity of the sea water is more or less constant though there may be minor differences caused by depth and deep sea currents etc.

Answer 3

Haller!!
the seawater is salty because the plants in the sea are releasing some salty particles that make the sea salty..
By the way, haller means excuse me!!

Answer 4

All rivers and tributaries that lead to the ocean (all of them!) deposit salt and silt into the ocean. Streams and freshwater sources also have salt, though just a bit. The concentration of salt in the ocean is much higher than the freshwater sources that feed it.

Answer 5

The two dominant ions used to create salt come from 1) sodium: which was leached out of the ocean floor when oceans were first formed. and 2) chloride, results from "outgassing" of chloride (as hydrochloric acid) with other gases from Earth's interior via volcanos and hydrothermal vents.

Answer 6

salt

Answer 7

Because there is salt in it.

Answer 8

theres salt in it.

Answer 9

same reason why fresh water is unsalty... duh , silly person
