Quote:deep sea facts: -An estimated 50-80% of all life on earth is found under the ocean surface and the oceans contain 99% of the living space on the planet. Less than 10% of that space has been explored by humans. 85% of the area and 90% of the volume constitute the dark, cold environment we call the deep sea. The average depth of the ocean is 3,795 external m. The average height of the land is 840 external m. -The oceans cover 71% (and rising) of the Earth's surface and contain 97% of the Earth's water. Less than 1% is fresh water, and 2-3% is contained in glaciers and ice caps (and is decreasing). - 90% of all volcanic activity occurs in the oceans.
-The speed of sound in water is 1,435 external m/sec - nearly five times faster than the speed of sound in air. -Earth's longest mountain range is the Mid-Ocean Ridge more than 50,000 external km in length, which winds around the globe from the Arctic Ocean to the Atlantic, skirting Africa, Asia and Australia, and crossing the Pacific to the west coast of North America. It is four times longer than the Andes, Rockies, and Himalayas combined.
-The pressure at the deepest point in the ocean is more than 11,318 external tons/sq m, or the equivalent of one person trying to support 50 jumbo jets.
