Most Extreme Places on Earth
Lut Desert (Iran): hottest place on Earth at 159 °F (71 °C)
Mt. Chimborazo (Ecuador): highest point above Earht's center at 20,703 feet (6,310 m) above sea level
But not many people know about Mt Chimborazo in Ecuador with an altitude of 6,310 meters (20,703 feet), which is less than Mount Everest; however, Chimborazo has the distinction of being the highest mountain above Earth's center. This is because Earth is not a sphere - it is an oblate spheroid. As an oblate spheroid, Earth is widest at its equator. Chimborazo is just one degree south of Earth's equator and at that location it is 6,384 kilometers from Earth's center or about 2 kilometers farther from Earth's center than Mount Everest.
Ecuadorians find pride in this interesting fact. Nonetheless, Chimborazo cannot compare in difficulty, lack of oxygen, nor in fame, to Mount Everest.
Tristan de Cunha (UK): most remote inhabited archipelago on Earth at 2,000 miles from the nearest continent
Oymyakon (Russia): coldest inhabited place on Earth at −96.2 °F (−71.2 °C)
The lowest temperature ever recorded on Earth was -129 °F in 1983, at the Russian Base Vostok in Antarctica.
The Dry Valleys (Antarctica): driest place on Earth
Another driest place is the Atacama Desert in Chile, some parts of which have received absolutely zero precipitation in centuries. Parts of the Atacama Desert may actually exceed the dryness of most of Antarctica, though data from the latter is insufficient to tell.
Marianas Trench (Indonesia and Japan): lowest point on Earth at 35,840 feet (10,924 m) below sea level
Lloro (Colombia): wettest place on Earth
So, which is wetter? It really depends on measurement practice and procedures and the period being measured!
