Tectonic Plates and Geological Processes

The video explores Virginia's geological history, highlighting the movement of Earth's supercontinents and the forces driving plate tectonics. It explains subduction, where oceanic crust slides beneath continental crust, leading to mountain formation like the Appalachians. The video also covers rifting, where continents fracture and form new oceans, and discusses the ongoing processes of continental drift and geological dynamics shaping our planet today.

What was the primary force driving the movement of Earth's supercontinents 400 million years ago?

• Ocean currents
