Avalanche. Avalanche pouring down a gully on Mount McKinley,Alaska,USA. Avalanches occur when large amounts of snow and ice become loose and flow down a mountain under the force of gravity. They can be extremely destructive. As well as the force of the snow and ice themselves,the wave of air in front of the rapidly-moving snow (the avalanche wind) can cause buildings to explode before the avalanche hits them. Mount McKinley is the highest mountain in the USA,reaching a height of 6194 metres | |
