Extremes on Earth

The Tallest Mountain (above sea level) – Mount Everest (Himalayas)
It stands 8848m above sea level!!!!

The Tallest Mountain (from base to summit) – Mauna Kea (Hawaii)
If the height is measured from base to summit, Mauna Kea defeats Mount Everest as the tallest mountain on Earth. Its base is 5800m below sea level, whereas its summit is 4205m above sea level, bringing its total height to about 10000m!!! (Mount Everest is only 3650m~4650m if measured from base to summit because its base is above sea level…)

The Farthest point from the center of Earth – Chimborazo (Ecuador)
This volcano only stands at 6267m above sea level, yet it is farther from the Earth’s core compare to Mount Everest. It is because Earth bulges at the Equator…. The peak of Chimborazo is 6,384.4 km from Earth’s core, farther than Mount Everest from earth’s core by 2168m!!

The Deepest point on Earth – Challenger’s Deep (Mariana Trench, Pacific Ocean)
Challenger’s Deep has a depth about 11000m. The pressure at this depth is approximately 110MPa, it is 1095 times that at the surface!!!!

The Saltiest water on Earth – Lake Asal (Djibouti)
Lake Asal is the most saline body of water on earth with 34.8 percent salt concentration (at a depth of 20 meters, as much as 39.8 percent has been measured). This is even more than that of the Dead Sea (around 31 percent of salt concentration).

The Coldest Temperature recorded on Earth - −89 °C (Recorded at the Russian Vostok Station in Antarctica)

The hottest temperature recorded on Earth - 58 °C (Recorded in El Azizia)
