The ocean plate was once the seafloor of Neotethys — an ocean that formed when the supercontinent Pangaea broke up into a ...

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 ...

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 ...

Different elements are present in different parts of the Earth’s structure. The crust is made from enormous plates which move very slowly due to movements of the mantle below. The Earth's structure.
