A Change of Scenery

The video explores the concept of change, focusing on how Earth's landforms are constantly evolving. It explains the movement of tectonic plates and how they contribute to landform changes. The video also discusses the processes of erosion and weathering, using examples like the Grand Canyon and Mount St. Helens to illustrate both gradual and rapid changes. The Old Man of the Mountain serves as an example of gradual change over millions of years. The video concludes by emphasizing that Earth's surface is always changing, whether quickly or slowly.
