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 ...

Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

This study is led by Prof. Yong-Fei Zheng at University of Science and Technology of China. It focuses on the development of tectonic processes along convergent plate margins through inspection of ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

Scientists say they have evidence of a new continental rift forming in southern Africa that could eventually develop into a ...

Renaissance polymath Leonardo da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force. When two objects are ...

It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...

Mars An anomaly in Mars' mantle could trigger volcanoes to erupt — and may be causing the whole planet to spin faster Mars NASA's Curiosity rover finds a surprising number of giant 'dragon scales' ...

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

The Earth’s crust is constantly changing. It’s currently made of many huge rock slabs called tectonic plates—seven major ones along with many more smaller plates—that fit together like puzzle pieces ...
