Exploring the Geological Forces Behind the Grand Canyon

The video explores the dynamic processes of plate tectonics, highlighting the formation of the Alps and the Himalayas through continental collisions. It delves into the geological history of the Grand Canyon, revealing how layers of rock tell the story of Earth's past. The video also discusses the evidence of ancient oceans found in the canyon and explains how the Colorado River carved the Grand Canyon over millions of years.
