It’s a simple and popular science class experiment: a volcano made with baking soda and vinegar erupts, spewing foam onto the table. In Germany’s Eifel region, viewing the power of volcanic forces ...

Basalt, the dominant volcanic rock along the Pacific Ocean's "Ring of Fire," is considered a melting product of the Earth's mantle. On the left is vesicular basalt, in which dissolved gases formed ...

Geoscientists have long thought that water -- along with shallow magma stored in Earth's crust -- drives volcanoes to erupt. Now, thanks to newly developed research tools, scientists have learned that ...

The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

ITHACA, N.Y. – Geoscientists have long thought that water – along with shallow magma stored in Earth’s crust – drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, ...
