Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ...

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...

Jack looks at projections of Earth’s continents far into the future, exploring geological and plate tectonic predictions for ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise ...

The two halves of the African continent are moving apart at a rate of a few millimeters each year, geologists have calculated ...

The Earth's crust is composed of approximately 15 to 20 tectonic plates, which float on molten magma beneath the Earth.

Scientists have traditionally focused on volcanic arcs as the main natural source of atmospheric carbon dioxide. These form ...

Three of the great tectonic plates that make up the Earth’s crust meet at the Mendocino Triple Junction, off the Humboldt ...

For decades, scientists have theorized that the movement of Earth's tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.
