Web27 de fev. de 2024 · Volcanoes are formed when magma, which is molten rock, rises to the surface of the Earth. Magma is created deep within the Earth’s crust by the melting of rocks due to high temperatures and pressures. As the magma rises, it can create a vent or opening in the Earth’s surface. This vent can then erupt, spewing out ash, lava, and gases. Lava cones are nearly unique to Bougainville Island in Papua New Guinea, within the Melanesia subregion of Oceania. However, an unnamed group of seven lava cones is located in the Obul-Samarask upland of southern Georgia, in Western Asia. The cones are early Pleistocene to Holocene in age. Many of the craters have a well-preserved morphology. The tallest is 3,400 metres (11,200 ft).
