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. Many believe it is in Al Azizyah, Libya, with a recorded of 136 degrees Fahrenheit (57.8 Celsius), and the second hottest place being in Death Valley, California, USA, where it got up to 134 Fahrenheit in 1913. But according to other sites, a NASA satellite recorded surface temperatures as high as 71 °C (159 °F) in the Lut desert of Iran, supposedly the hottest temperature ever recorded on the surface of Earth. This region, which covers an area of about 480 kilometers, is called Gandom Beriyan (the toasted wheat).
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 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 is the . Climbers from everywhere travel to Everest hoping to earn the distinction of climbing the "World's Highest". The peak of Mount Everest is 8,848 meters (29,028 feet) above . This high elevation gives Mount Everest the distinction of being the mountain with altitude.
Angels Falls (Venezuela): Earth's highest waterfall with 3230 feet (984 m) in height, Tristan de Cunha in the southern Atlantic Ocean, is so tiny its main island has no airstrip. Home to 272 people sharing just 8 surnames, inhabitants suffer from hereditary complaints like asthma and glaucoma. Annexed by the United Kingdom in the 1800s, the island's inhabitants have a British postal code and, while they can order things online, it takes a very long time for their orders to arrive. But then, that's the trade off for having your own island settlement some 2,000 miles from the nearest continent.
Oymyakon (Russia): coldest inhabited place on Earth at −96.2 °F (−71.2 °C)
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!
Mount Thor (Canada): Earth's greatest vertical drop
Dead Sea (Jordan and Israel): Earth's lowest elevation at 1,385 ft (422 mt) below sea level
