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, ...

Plate tectonics is the means through which mountains are formed. The Baird Mountains in Alaska's Kobuk Valley National Park formed when two tectonic plates along a convergent boundary collided, ...

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 ...

W. Jason Morgan, a Princeton University geologist who laid out an influential new vision of our evolving planet, attributing the most powerful upheavals — earthquakes, volcanoes and the formation of ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...
