Specific purpose: The audience will know that the Dead Sea is devoid of all plant and aquatic life, why the sea is so salty and the health benefits. Thesis or central idea: The Dead Sea has a unique environment Main Points: a. The Dead Sea is one of the saltiest bodies of water anywhere b. The Dead Sea is devoid of all plant and aquatic life c.
The Dead Sea area has become a major center for health research and treatment Introduction: You know why they call it the dead sea? Because absolutely nothing live in it. It is some of the sales 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 sales 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 sales 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 dissolved 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'. 1. Black mud is a natural product of the Dead Sea. The mud is now marketed worldwide, often advertised with images and text evoking the mystery, symbolism, legend, and history associated with a region sacred to three of the world's major religions People suffering from Psoriasis have found the Dead Sea atmosphere and swimming in the sea very helpful. Smearing mineral rich Dead Sea Mud on the body, provides a healing process for the skin, and broadens the capillary veins. It is known that King Solomon, Queen Cleopatra and Herod the Great all visited the Dead Sea for these cures. B.
The atmosphere of the Dead Sea is unusually rich with oxygen, magnesium, and bromide, minerals. 2. This improves the delivery of oxygen to the heart and lungs, thus improving patients' cardiac performance. 3. Cystic fibrosis, a genetic disease that causes mucus to form in part of the lungs and predisposes the patient to chronic lung infections. The Dead Sea's high oxygen level led to the patients having more oxygen in their blood, therefore improving the efficiency of breathing for cystic fibrosis patients. This made them more able to exercise and enjoy daily life. 4. The extraordinarily high concentration of minerals found in the Dead Sea's mud, sulfur pools, thermonuclear springs and surrounding atmosphere also aided the breathing of patients with respiratory problems and pulmonary disorders. 5.
Due to evaporation, the unusually high levels of minerals in the atmosphere at the Dead Sea make the surrounding air not only rich in oxygen, but also free of pollen and the sun's harmful rays Conclusion: I hope that with this little bit of information you now have a better understanding of my fascination with the Dead Sea and its unique environment Sounds kin da creepy, doesn't it? It's called the Dead Sea because nothing lives in it. It is some of the saltiest water anywhere in the world, almost six times as salty as the ocean! The Dead Sea is completely landlocked and it gets saltier with increasing depth. The surface, fed by the River Jordan, is the least saline. Down to about 130 feet (40 meters), the seawater comprises about 300 grams of salt per kilogram of seawater.
That's about ten times the salinity of the oceans. Below 300 feet, though, the sea has 332 grams of salt per kilogram of seawater and is saturated. Salt precipitates out and piles up on the bottom of the sea. There's no seaweed or plants of any kind in or around the water.
There are no fish or any kind of swimming, squirming creatures living in or near the water. As a matter of fact, what you " ll see on the shores of the Sea is white, crystals of salt covering EVERYTHING. And this is no ordinary table salt, either. The salts found in the Dead Sea are mineral salts, just like you find in the oceans of the world, only in extreme concentrations.
The water in the Dead Sea is deadly to living things. Fish accidentally swimming into the waters from one of the several freshwater streams that feed the Sea are killed instantly, their bodies quickly coated with a preserving layer of salt crystals and then tossed onto shore by the wind and waves. Brutal! The guy to the left is actually floating in the Dead Sea. 'But, hey, I thought you said the Dead Sea was DEADLY!' Not to us.
Humans are remarkably adaptable. We can swim in the Dead Sea, just like we can swim in the ocean. Well, people don't really 'swim' in the Dead Sea - they just 'hang out'. That's what's so cool about the Dead Sea. Because of the extremely high concentration of dissolved mineral salts in the water its density is way more than that of plain old fresh water. What this means is our bodies are more buoyant in the Dead Sea - so you bob like a cork.
In fact, people are so buoyant in this water, it makes it kinda tough to actually swim. Most people like to just kick back in the water and read. It almost looks as though this guy is sitting on an air mattress that has sunk below the surface, but he's not. He's really just floating, without having to hold is feet in that position! If you think this is easy, try floating like this in a freshwater swimming pool Anyway, back to the formation of the Dead Sea. We talked about how the surface of the Sea got down so low in elevation, but why is it so salty?
All roads lead to the Sea when it comes to the rivers in the area. The Dead Sea is continually fed water from the rivers and streams coming down off the mountains that surround it. But the kicker is this... no rivers drain out of the Dead Sea.
The only way water gets out of the Sea is through evaporation. And boy does it evaporate! This part of the world get plenty hot. When the water evaporates, it leaves behind all the dissolved minerals in the Sea, just making it saltier.
In fact, it's through the dual action of; 1) continuing evaporation and 2) minerals salts carried into the Sea from the local rivers, that makes the Sea so salty. The fact that the water doesn't escape the Sea just traps the salts within its shores. There's nothing living in the Dead Sea because it got so salty, so quickly, that evolution has not had a chance to produce any creatures that could adapt to such brutal conditions.
