Tectonic Plates and Their Dynamics

This video explains tectonic plates, their types, movement, and consequences. Tectonic plates are fragments of the Earth's lithosphere, floating on the asthenosphere. They can be oceanic or continental, and their movement is influenced by factors like the geothermal gradient. The movement leads to phenomena such as volcanoes, earthquakes, and mountain formation. The video concludes with a quiz to test understanding.
