Mount Everest

Mount Everest

The official altitude of the world's highest peak Mount Everest is 29,029 feet (8,848m). However, the National Geographic Society has determined the height to be 6 feet taller, 29,035 feet, but the Nepali government has not yet been made this new altitude official.

Shifting tectonic plates continue to push Mount Everest upward, along with the whole Himalaya mountain range, at 1.6 to 3.9 inches (4 to 10 centimeters) per year.

The Great Wall of China is not a continuous wall but is a collection of short walls that often follow the crest of hills on the southern edge of the Mongolian plain. The Great Wall of China, known as "long Wall of 10,000 Li" in China, extends about 8,850 kilometers (5,500 miles).
