Separating Solutions and the Salty Sea
Why is the sea saltier than rivers?
What is desalination?
What do the Salton and Aral Seas have in common?
What environmental problems do they have?
It is widely believed that the term "salary" was derived from the Latin word for salt. Based on what you read in this article, why might this be true?

1. The Sea is saltier than rivers because the sea evaporates and leaves behind the salt.
ReplyDelete2. Desalination is when salt leaves water to make fresh water.
3. The Salton and Aral Seas both have very high salt levels.
4. If the salt level gets too high then almost no organisms can live there.
5. The word "salary" may come from the word salt because it has been going on for many years and has helped people gain a lot of money.

1. Heat from the sun evaporates water on the sea and leaves a higher concentration of salt in the water.
ReplyDelete2. Desalination is the removal of salt from water.
3. In both the Aral and Salton seas the water salinity is at fatal or near fatal levels for sea organisms
Seas are saltier than rivers because the waters in the sea, the soluble substences are concentrated, and during evaporation the salt is left behind, the seas become salty over a long period of time. This might be true because salt was very valuable and during trades was like money.
ReplyDelete1) The heat from the sun evaporates the water in the sea and makes the salt from soluble substances increase in amount. Water from rivers and streams eventually pour out into the sea so the salinity within the sea is far more substantial.
ReplyDelete2) Desalination is the removal of salt from water.
3)The Salton and Aral Seas are both very salty seas.
4) No living organisms can survive in either of these seas.
5) The word salary may have been derived from the Latin word for salt because of all of the money that was earned from trading high valued salt.
