Glacier National Park - Erosion and Preservation of the Water Table

The video explores how vegetation in Glacier National Park affects erosion. It guides students in building a simple model to simulate erosion using soil and grass on inclined trays. Students are encouraged to make predictions and observe results. The video highlights the importance of soil nutrients and plant roots in preventing erosion and discusses the park's efforts to restore native vegetation to maintain delicate ecosystems.
