Glaciers: Forming and Deforming Ice Rivers

Explore the animated tutorial on glacier formation and deformation, including types and movement. Discover the process of V-shaped valleys transforming into U-shaped valleys due to glacial erosion. Learn about the formation of glaciers, their movement, crevasse formation, and glacier retreat's impact, illustrated with detailed animations and real-world examples. Follow the link for an in-depth educational experience.
