Question

Most lakes have rivers flowing out of them, carrying water to the ocean. However, some lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into these lakes leaves only through evaporation. Considering that the water flowing into the lakes contains many dissolved substances, how does the lack of an outlet affect the composition of these lakes? What would you expect to happen after many more years of inflow and evaporation?

Answer 1

Salt lakes ,Great salt lake or Dead sea all are derived lakes from sea water .

• The water is not drinkable
• As salt concentration is more than average it can only flow through evaporation
• There is no other way to make them flow .
• After many more years they may be empty because of lack of rain there and evaporation speed

Answer 2

Since the only way of water flow to these lakes or bodies of water is through evaporation, I would expect an increase in unknown substances in the composition of the lakes due to the amount of contamination that globalization produces and affects terribly the surroundings when these unknown substances travel through evaporation as the outlet of these bodies of water. Therefore I think continuous contamination is what to expect after many more years of inflow and evaporation.
