A large mass of material falling or sliding rapidly due to the force of gravity. In many cases, water acts as a catalyst and/or lubricant. Avalanches often are classified by what is moving, such as a snow, ice, soil, or rock avalanche. A mixture of these materials is commonly called a debris flow.

Movement down the mountain of previously stationary snow, rock, or both. Snow avalanche conditions for open slopes can often be predicted by monitoring the weather.
