Disclaimer: I'm no Danish teaching expert, I just happen to be an Icelander who was forced to learn Danish as my second language - and although I always got very good grades in Danish, I was never good in Danish: can't speak it, can't understand a Dane - I can maybe read it a little bit...
University of Utah geology and geophysics professor Fan-Chi Lin said the blob-shaped lower magma reservoir in Earth's lower crust is located 12 to 28 miles (20-45 km) under Yellowstone, with a volume of 11,500 cubic miles (46,000 cubic km), or 11.2 times the volume of Arizona's Grand Canyon.
A hot plume of mantle lies just beneath Yellowstone National Park and itâs the heat from the mantle that melts the overlying rocks forming what is known as volcanic hotspots, which can erupt. In fact Yellowstone is considered the worldâs largest super volcano.It has had three titanic eruptions (luckily all in the prehistoric past) some 2.1 million, 1.3 million, and 640,000 years ago. Each event spread at least a thousand cubic kilometers of ash and lava.Smaller Yellowstone eruptions, mostly consisting of just slow moving lava flows, have occurred more frequently.t has had three titanic eruptions (luckily all in the prehistoric past) some 2.1 million, 1.3 million, and 640,000 years ago.
