Did you know?
WebMolten rock, i.e., magma, is less dense and more buoyant than the surrounding rock, as a result magma rises through Earth's crust. Most magma is trapped in the crust, but some erupts onto the Earth's surface as lava. There, I've synthesized 100 years+ of geologic studies of magma formation into 4 short paragraphs. http://www.columbia.edu/~vjd1/subd_zone_basic.htm
WebHá 3 horas · Jupiter’s magma and volcano covered moon Io might also be host to all of the recipes for alien life. It’s likely to be a target for yet another future moon mission to the gas giant. A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. If the magma finds a path to the surface, then the result will be a volcanic eruption; consequently, many volcanoes are situated over magm…
