Plate Tectonics and Boundaries

The video discusses the theory of plate tectonics, explaining that Earth's surface is made up of moving plates atop the viscous mantle. It covers three types of plate boundaries: transform, divergent, and convergent. Transform boundaries involve plates sliding past each other, as seen in the San Andreas fault. Divergent boundaries occur where plates spread apart, forming new crust at mid-ocean ridges and rift valleys. Convergent boundaries involve plates colliding, leading to subduction or mountain formation, exemplified by the Himalayas. The video concludes with a brief summary of these movements.
