Located between Nepal and Tibet in the Himalayas range in Asia, Mt. Everest is the highest point on Earth. Its peak is 29.035 ft above sea level. The Mariana Trench in the western Pacific Ocean is the deepest natural point at 36, 201 ft below sea level.
Oxygen, needed to sustain animal life, comprises about 20.9 percent of the Earth’s atmosphere. Above 26,000 feet, the air contains insufficient oxygen to support human life. Climbers ascending the tallest mountains must bring breathing oxygen with them.
Below the surface of the sea, water pressure increases rapidly. At a depth of 33 feet (10 meters), the pressure increases to two atmospheres (that is, equal to twice the pressure of air at sea level. Every 33 feet, the pressure increases by one atmosphere.
Oceans cover about 71 percent of the Earth’s surface and support 50 percent of Earth’s species of life. The average depth of the ocean floor is 12,080.7 feet (3,682.2 m).
