Dead Sea


The Dead Sea is a very scary name for a lake. It is called so because nothing lives in it. There are no sea weeds or plants, no fish either. This is because the Dead Sea is nearly six times as salty as the ocean.

Why is sea water salty?
Many minerals like Sodium, Chlorine, Magnesium and Silica are found on the surface of Earth. Every time it rains, tiny amounts of these minerals are carried into rivers, and ultimately to the seas, along with rainwater. The two most abundant elements in sea water are Sodium and Chlorine. These combine to form salt, making the sea (and ocean) water salty.
