The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves 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 ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Earth surface is covered with rigid plates that move, crash into each other and dive into the planet's interior. But when did this process begin? When you purchase through links on our site, we may ...

Minerals suggest large blocks of Earth’s crust moved around as early as 3.2 billion years ago Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million ...
