What is the lowest elevation on all the seven continents?

Answer 1

The Dead Sea in western Asia between the West Bank and Jordan. The surface of the Dead Sea is 1,300 feet below sea level. The deepest part of the very bottom of the sea is 2,300 feet below sea level. Since it is so low there are no rivers to drain out impurities in the Dead sea and most of the impurities would fall into the Dead Sea by gravity where it can't fall anywhere else. The Dead Sea is one of the saltiest seas in the world, even saltier than the Earths oceans. 35% of the water is dissolved salts. The only way water can escape the Dead Sea is by evaporation which leaves out the impurities behind, where the Dead Sea would have more of a concentration of salt and impurities. In the surface of the Dead Sea the air pressure is extremely high, and the highest in the world, since there is so much air molecules. The sky could look much more of a brighter blue, reflecting more sunlight, and sunsets may look more redder. Since there is so many air molecules the temperatures in the Dead Sea are normally high but since it has a water source where water has a higher heat capacity it doesn't really reach temperatures that are as hot as Death Calley in California.

Answer 2

The lowest elevation on all seven continents is the shoreline of the Dead Sea in Asia, which sits at approximately 430 meters (1,411 feet) below sea level.
