The correct answers are:
C. I and IV.
- The dry climate encourages the water to evaporate;
- More water is being siphoned off the Jordan River for agriculture;
The Dead Sea is well know around the world as the sea where there's no life, the sea in which you can not sink, the sea that is the saltiest in the world (it is up there around the top but it is not the saltiest). It is bellow the surface of the sea, and it is located in a very arid region. Since its main tributary, the Jordan River has started to be used much more for agriculture, the Dead Sea started to get lesser amount of water in it. Because of this, and the scorching heat, the evaporation has become greater than the influx of water, thus making the waters gradually retreat. If this continues, the Dead Sea will be perished in the very near future.
