Water stored in the mantle for millions of years may be linked to continental volcanism
The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

What Killed the Dinosaurs?
According to the volcanism hypothesis, this global-scale volcanic activity spewed so much gas, ash, and dust into the atmosphere that it kept sunlight from reaching Earth's surface. Temperature ...

Submarine Volcanism
Most volcanism on Earth occurs beneath the oceans, but submarine volcanoes are difficult to study. Advances in seafloor monitoring have opened up an unprecedented view of eruptions on the seabed.
