To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine is ...

Scientists studying Greenland have uncovered surprising heat variations deep beneath the ice that could reshape experts' understanding of future sea-level rise. The discovery, made using advanced 3D ...

Plate tectonics has shaped the Earth’s surface for billions of years: Continents and oceanic crust have pushed and pulled on each other, continually rearranging the planet’s façade. As two massive ...

Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. Scientists created a core growth model to ...

3D models in Google Earth have been getting better and better every week, but one key area always remains unfinished — the inside. Modeler ‘PeterG’ has finished modeling the inside of the Leku ...

Deep in the Earth beneath us lie two blobs the size of continents. One is under Africa, the other under the Pacific Ocean. The blobs have their roots 2,900 kilometers below the surface, almost halfway ...
