Introduction: You know why they call it the dead sea? Because absolutely nothing live in it. It is some of the salties water anywhere in the world. My love for geology grew out of an experience with a friend whos child was doing a earth science project on plate tectonics and needed help. I’ll never forget the name of the book “Earth in Motion” it left a lasting impression on me and led me to study more on this subject. I’ve been reading about this for approximately 10 years and am always amazed at the new material I find . My latest discovery was that the Dead Sea is one of the salties bodies of water anywhere, that it is devoid of all plant and aquatic life and that it has become a major center for health research and treatment.

I. The Dead Sea is one of the salties bodies of water anywhere
A. The Dead Sea is completely landlocked
B. The Dead Sea is continually fed water from the rivers and streams coming down off the mountains that surround it.
1. No river drains out of the Dead Sea
2. The only way water gets out of the sea is through evaporation

II. The Dead Sea is devoid of all plant and aquatic life
A. The water in the Dead Sea is deadly to most living things
B. Even though the Sea is deadly to most living things humans are remarkably adaptable to the seas salty conditions. Humans can swim is the Dead Sea, just like they swim in the ocean
1. Humans don’t really swim in the sea, instead they just “hang out
2. Because of th extremely high concentration of disolved mineral salts in the water its density is way more that that of fresh water, which means are bodies are more buoyant in the Dead Sea.

III. The Dead Sea area has become a major center for health research and treatment
A. The Dead Seas deep black clayey sediment, previously covered with water at times of higher sea level, are being mined for therapeutic purposes and for the preparation of cosmetic products under the name ‘Black Mud’.
