The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. 4 min read There are a few handfuls of major plates and dozens of smaller ...

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 ...

Plate tectonics is a perfect example of this. Space view of Earth's magnetic rocks Mapping Earth's slow surface warping Gravity satellite probes deep Earth It tells us why the Himalayas are so ...

Plate tectonics, or the recycling of Earth’s crust, may have begun much earlier than previously thought—and may be a big ...

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 ...

Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under the Earth’s crust transfer heat, which rises through ...

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 ...

Dynamic Earth clearly details the mechanisms responsible for plate tectonics, volcanic hotspots, and many resulting geological processes. Starting from basic principles, coverage provides a ...

Also known as spreading boundary, a divergent boundary occurs where two plates move apart, allowing magma, or molten rock, to rise from the Earth's interior to fill in the gap. The two plates move ...
