The video provides a comprehensive overview of plate tectonics, explaining the theory's principles, historical development, and supporting evidence. It covers the characteristics and movement of tectonic plates, types of plate boundaries, and the forces driving plate movement. Key concepts include continental drift, ocean floor expansion, and mantle convection. The video also highlights the main tectonic plates and their interactions, offering insights into geological processes like earthquakes and volcanic activity.

What is the primary reason for the movement of tectonic plates?

• Gravitational pull from the moon

• Heat transfer from the Earth's core and mantle
