Once inside the oceanic mantle, bits of continents become part of the magma factory that powers ocean volcanoes.

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.

Scientists have long wondered how volcanoes formed in central Anatolia despite being far from tectonic plate borders—now they've found evidence of a hot plume of magma flowing from East Africa. Riders ...

Underwater volcanoes are powerful geological forces shaping our planet and oceans. These hidden giants form through tectonic ...

For hundreds of millions of years, Earth’s climate has warmed and cooled with natural fluctuations in the level of carbon dioxide (CO₂) in the atmosphere. Over the past century, humans have pushed CO₂ ...

The Ring of Fire is an area around the Pacific Ocean that traces the boundaries between several tectonic plates. Also referred to as the Circum-Pacific Belt, this path is approximately 25,000 miles ...

Venus is sometimes called Earth’s twin, as it is roughly the same size as Earth, occupies the orbital lane adjacent to ours, and has a problem with greenhouse gases (namely carbon dioxide) in its ...

Among seismologists, the geology of Alaska's earthquake- and volcano-rich coast from the Aleutian Islands to the southeast is fascinating, but not well understood. Now, with more sophisticated tools ...

Like the volcano planet Mustafar from Star Wars, half of the exoplanet 3844b could be covered in active volcanoes. This planet, discovered in 2019, could be the first world we know, outside the solar ...

We've gone to the bottom of the ocean to study how its chemistry shapes our planet's climate, even chasing lava-spewing ...

The east coast of North America was once as wild as the West, with massive mountains rising between colliding tectonic plates, volcanoes belching lava and giant faults slicing the crust. That's ...

Deep below the Earth's surface, magma is churning and flowing into the Axial Seamount, an underwater shield volcano about 300 miles off the coast of Oregon. As the volcano grows and tremors increase, ...
