Does water cycle ensures that seas do not get more salty?

Answer 1

Yes. The current salinity is kept in balance by the equilibrium of evaporation, which makes it more salty, and rain fall and river run-off which dilutes it.

Answer 2

First you may desire to look on the water cycle, (a million) organic water evaporates from the sea and turns right into a cloud, (2) the cloud rains over land (3) the water drains to rivers and streams, as they try this (4) and because water is a organic solvent, (5) the water collects minerals and organic salt from the land (6) and those is deposited interior the sea via streams, and rivers (7) because of the fact this technique became repeated on a daily basis for billions of years, there are a great concentration of dissolved organic salt interior the sea. ultimately look at an excellent technological expertise e book. i'm hoping that the above tough thought helps you why and how the sea grow to be salty.

Answer 3

No;in fact, water cycle adds more and more salt to the sea.Water cycle includes the entry of water into the atmosphere(in the form of water vapour) by evaporation from the water surfaces and transpiration of the plants and the vapour returns to earth as rain and snow.
During evaporation from the sea,salt is always left behind.So, in future, the amount of salt in seas and oceans will increase only.
Man may remove some salt from the sea for consumption.But that will be negligible.
