1:Aogashima, The Inhabited Volcanic Island of Japan
Aogashima is a volcanic island 3.5 km in length with a maximum width of 2.5 km, formed by the overlapping remnants of at least four submarine calderas. The island is surrounded by very steep rugged cliffs of layered volcanic deposits. The southern coast also rises to a sharp ridge forming one edge of a caldera named Ikenosawa with a diameter of 1.5 km. The caldera dominates the island, with one point on its southern ridge, Otonbu with a height of 423 metres (1,388 ft), as the island’s highest point. The caldera is occupied by a secondary cone named Maruyama.
Aogashima is a tropical volcanic island in the Philippine Sea, administered by Tokyo despite being located approximately 358 kilometres (222 mi) south of Tokyo. It is the southernmost and most isolated inhabited island of the Izu archipelago.
2:The highest point on Earth
Mount Everest, part of the Himalayan range in Nepal, is the highest peak above sea level with 8,848 metres. It usually takes climbers over a month to acclimatize before occupying arguably the most extreme of the most extreme places on Earth.
3:Venezuela Angel Falls
It is the world's highest uninterrupted waterfall, with a height of 979 metres (3,212 ft) and a plunge of 807 metres (2,648 ft). The waterfall drops over the edge of the Auyantepui mountain in the Canaima National Park (Spanish: Parque Nacional Canaima), a UNESCO World Heritage site in the Gran Sabana region of Bolívar State.
4:Badwater Basin in Death Valley National Park, the lowest spot in North America.
For the record, the Dead Sea, between Israel and Jordan, is the lowest spot on Earth at 1,371 feet (418 m) below sea level.Badwater Basin, in Death Valley National Park, is the lowest place in North America and one of the lowest places in the world at 282 feet (86 m) below sea level. This elevation is the result of geological forces that began stretching the western margin of North America about 16 million years ago and eventually deformed the Death Valley area into an alternating series of trough-like basins and towering ranges.
5:Krubera Cave
The Krubera Cave is the deepest known cave on Earth, -2.191 metres. It is located in the Arabika Massif of the Gagrinsky Range of the Western Caucasus, in the Gagra district of Abkhazia, north-west of Georgia.
