Why is sea water salty and river or lake water is never salty?????????

Question

Please help me and give short and to the point answers!!!!
Thanx!!!!!!!!

Answer 1

when rain falls on the earth, the water dissolves the minerals & may reach the rivers , lakes or oceans.

the river water is continuously flowing & reaches the ocean or sea carrying with it the dissolved minerals. the volcanic eruptions also deposit some amount of salts in to the sea.Sun evaporates the water & the water vapour goes into the water cycle to bring fresh amount of rain water which again dissolves more salts & reaches the rivers & seas. since the water from the seas evaporate leaving behind the salts ( this has been happening for over millions of years ), the sea water is more salty (about 35 grams / litre ) than the other water sources.
In dead sea the amount of salt is too high, for any aquatic organisms to survive.

Answer 2

Contrary to some others said, continental run-off carrying salts to the oceans is not the main reason why they are salty. The real reason is because of white smokers and black smokers. These volcanically heated vents circulate ocean water and transfer ions from lava into the water. When the vents release the water some of the elements precipitate into minerals but most of them stay in solution, thus making ocean water salty. Oh, and contrary to your statement, there are many lakes that are salty. The Great Salt Lake in Utah is a good example. They are salty because they have internal drainage and have no way to discharge the salts, thus they become saline (salty).

Answer 3

River or lake water isn't salty because it is "fresh" water, derived from rain or snow that fell over the land.

This rain came originally from the oceans but during the evaporation process from the sea to the air, the salt was left behind.
This is where salt deposits came from, the seas evaporated and left the salt behind, sometimes many feet thick.

Answer 4

Sea water is essentially the same water that flows from rivers. However, as the river travels along, it picks up minerals such as salt from the riverbed and banks. The same action as picking up silt and muds. When this hits the oceans, the water evaporates, leaving the salts behind in the remaining water.

Answer 5

The river moves with a greater amount of velocity,thus avoiding deposition of salt through its source.Sea water is steady thus depositing more salt.

Answer 6

Easy.

God wants us to drink lake and river water, so it is not salty. He doesn't want us to drink water from the ocean, so it is salty.
