How much land does the desert cover?
True deserts cover about 14 percent of the world’s land area, or about 8,000,000 square miles (20,800,000 square kilometers). Another 15 percent of the Earth’s land surface possesses some desertlike characteristics.

On what percentage of the world is the extent of warm deserts?

Can humans drink sea water?
Why can’t people drink sea water? Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.
Where is the warmest water found?
Answer: The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.
What type of salt is in the ocean?
The orange salt ring is the most soluble salt. As water evaporates from seawater, the salinity of the remaining solution increases….SF Table 2.1.
