Slab Avalanches. The two main avalanches are loose snow and slab avalanches. These two types of avalanches are distinguished by the snow condition at the origin. However, sometimes classifications must be modified on long avalanches, due to the fact that snow conditions vary throughout the avalanche.
However, wind alone will not cause a slab avalanche. Gravity and the strength of the bonds between snow layers are important in slab avalanches. This is because gravity is the force which is pulling the slab down the mountain.
