What Causes Avalanches?

Many things can cause avlanches; for example, Weather, snowpacks, and terrians are just a few. Weather is one of the main things that can cause an avlanche, for one it creates the snow, and 2, if a sudden change in weather many things could go wrong. Snowpacks are layers of snow that have settled over time. If the bond between the layers are weak that's when most avlanches occur. Terrians, if a slope is too steep you can usually expect an avalanche to occur. On most low-angled slopes snow can start moving, but only if heavly packed. As on steep slopes, snow moves continuously.
