Avalanches

Headed off for a ski trip? Uncover the secrets of the mountains as Tim and Moby introduce you to the terrible power of avalanches. In this BrainPOP movie, you’ll discover how avalanches form and what makes them so destructive. Learn how the forces of stress and strength determine whether a mountain’s snowpack stays stable, and what happens when something disturbs that delicate balance. Discover what keeps a slab of snow in place on a mountainside, and what can make that same slab unstable. Finally, meet the “avalanche triangle,” and see what special property of snow can help it adjust to all sorts of situations. Go ahead and strap on those skis--just watch out for the slabs!
