Diverging and Sliding Plates

The video explains the concept of seafloor spreading, where two tectonic plates move apart, forming divergent boundaries and mid-ocean ridges. It highlights that most volcanic activity occurs along these boundaries. Transform faults, like the San Andreas Fault, are where plates slide past each other, causing earthquakes. The video also discusses convection currents in the Earth's mantle, which are believed to drive plate movement through temperature-induced material circulation.
