Avalanches are all about physics. According to scientists, the vast majority of avalanches occur on slopes between what angles?

30 to 45 degrees is the optimum angle for an avalanche to occur. That's because it's just steep enough for gravity to pull the snow down, but not too steep for snow to accumulate on the surface. Angles that get too steep are not ideal for snow build up so avalanches aren't as common.
