Earth's Changing Landscape: Constructive and Destructive Forces Explained

The video introduces fifth graders to the concepts of constructive and destructive processes that shape the Earth's surface. It explains how landforms are created through these processes, with examples like deposition, volcanoes, and earthquakes. The video also covers the historical concept of Pangaea, where all continents were once connected. Constructive processes build up the Earth's surface, while destructive processes break it down. Some forces, like volcanoes and earthquakes, can be both constructive and destructive.
