Geologists use the discipline of paleomagnetism to measure the Earth's magnetic field as it existed millions of years ago. When molten rock cools, magnetic minerals align with the planet's magnetic ...

Now, scientists have uncovered one of these missing pieces—the Pontus plate—shedding new light on Earth’s geological past and how the planet continues to evolve. The Earth’s crust is divided into ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

All of these processes result from plate tectonics, the movement of enormous chunks of Earth's crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...
