Face Of The Earth (1975)

This film explores the dynamic geological processes that shape the Earth's surface, focusing on the immense heat within the planet as the driving force. It explains how convection currents in the mantle cause tectonic plates to move, leading to the formation of mountains through volcanic activity and the buckling of crusts. The video also touches on the erosion of mountains by rain and rivers, the deposition of sediment to form new rock layers, and the continuous cycle of mountain building and destruction. Ultimately, it highlights that the Earth's surface is constantly changing, driven by internal heat and plate tectonics, leaving us with a profound geological mystery.
