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 ...

New research suggests that Earth's first crust, formed over 4.5 billion years ago, already carried the chemical traits we ...

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...

Your students will examine the locations of earthquakes, investigate why earthquakes occur and determine the value of being able to predict earthquakes. Distribute to students the CNN Student News ...

Scientists discovered Earth's first crust had continental chemical signatures. This challenges beliefs about when these ...

I can stare at a topographic map for hours and being amazed by how various features can be explained by the plate tectonics theory. I also feel deeply sad when large earthquakes or volcano eruptions ...

Geysers or hot springs of some kind were predicted at the Rift based on the relatively new plate tectonic theory. Remote sensors showed temperature changes and the presence of large clam shells ...

Their theory was based on seismic signals ... These discoveries suggest that the Pontus plate was once part of a unified ...

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 ...
