The researchers suspect these strange features form similarly to some of the volcanoes found here on Earth. Molten magma likely creeps up from planet's warm mantle, kind of like hotspot volcanoes that pop up in places like Hawaii and Yellowstone. And these things are massive; the average size...
How often does a shield volcano erupt?Shield VolcanoA shield volcano is a volcano that lies very flat with a wide base. The reason it is called a shield volcano is because the volcano has the appearance of a round shield.Answer and Explanation: ...
If there is a good deal of pressure, however, a volcano will begin its eruption with an explosive launch of material into the air. Typically, this eruption column is composed of hot gas, ash and pyroclastic rocks -- volcanic material in solid form. There are many sorts of explosive...

Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes...
How often does the Yellowstone hotspot create a new caldera? How fast does ocean warming happen? Where do tsunamis occur? How do deep ocean currents regulate climate? What is red tide caused by? How does an upwelling form from the Antarctic circumpolar current?

1 ARTICLE NATURE COMMUNICATIONS | DOI: 10.1038/ncomms8799 Although it has been proposed that some plumes have had constant compositions through time, such as the Louisville1 and Kerguelen2,3, spatial geochemical zonation has been found in a variety of hotspot tracks in the Pacific Ocean. These...
you're looking at a very unique case of geology. As with most things in life, there's no one fits all rule. You're looking at thinner crust, because it's oceanic not continental crust, that is rifting apart. Iceland formed due to a hotspot hitting the mid-ocean ridge and ...
