When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...

The puzzle pieces of Earth’s rocky crust are slowly and steadily moving — a process known as plate tectonics. These dynamic movements helped to create the habitats and climate that fostered the ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

A region known as the Kafue Rift could be the site of the world’s newest plate boundary, as the once stable African tectonic ...

There is something strange about Earth. A few billion years ago, a process started here that we have never seen anywhere else. It completely reshaped the planet’s surface and its carbon cycle, ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...

Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new ...

Scientists have discovered a long hidden plate boundary near the east coast of Africa that dates back about 180 million years ...

Planets Something supercharged Uranus with radiation during Voyager flyby 40 years ago. Scientists now know what. Geology Ancient process that created rare earth elements discovered — and it could ...
