For the more than 1,500 mountains worldwide with a prominence of over 1,500 meters (4,921 ft), the term "Ultra Prominent Peak" has become established. In the Himalayas, up to 500 meters is used as a criterion. In the European Alps, for example, a prominence of 30 meters is considered to be the standard for the independence of a mountain. Lake Vostok is roughly the size of North. Antarctica is also home to Lake Vostok, one of the worlds largest lakes. Here again, there are no uniform absolute values. In fact, there is an active volcano in Antarctica: Mount Erebus, which is 3,794 meters (12,447 feet) in height, is located in East Antarctica, on the edge of the Ross Ice Shelfa place where ice extends far out over the ocean. For the demarcation of two connected geoformations, the topographic prominence (shoulder drop) and dominance (distance between each other) are also used. Also, a mountain has an independence, so a large hill on a mountain plateau does not become a mountain itself. Mountains are usually steeper and higher. What is a mountain? There is no exact distinction between a mountain and a hill. It is the horizontal distance between two peaks. The "dominance" is also recorded in the classification of mountains. The drop is the deepest cut between the peaks. This is the relative height to the actual base of the mountain, which can also be a foothill of a plateau. The summit of the dominantly phonolitic volcano has been modified by one. It is the largest of three major volcanoes forming the crudely triangular Ross Island. Mount Erebus, the worlds southernmost historically active volcano, overlooks the McMurdo research station on Ross Island. Therefore, in addition to the absolute height, the topographic "prominence" is also measured, often called the autonomous height or shoulder drop. Erebus Antarctica 77.53°S, 167.17☎ summit elev. With a summit elevation of 3,794 metres (12,448 ft), it is located on Ross Island, which is also home to three inactive volcanoes, Mount Terror, Mount Bird. It is the 6th highest ultra mountain on an island. Prominence: Relative height to surroundings A small hill on top of a large mountain would have an extremely high peak just because of its surroundings - at least if you measure it in relation to sea level. Ross Island, Mount Erebus is the second highest volcano in Antarctica (after Mount Sidley) and the southernmost active volcano on earth.
