Wild Weather Kitchen Experiments: Avalanches

Updated Thursday, 19th March 2020

Ever wondered how avalanches occur? This video reveals the science behind this natural disaster.

While avalanches themselves are not strictly a weather event, the weather determines when snow conditions make avalanches more likely. Snowpacks of differing strength are built up over time and the interfaces between them can be lubricated by finer powder snow. Avalanches can be deadly, but sadly far more people are killed by mudslides and landslides. The processes involved are similar, with layers of rock or soil being lubricated by water.

In this video we will see why avalanches begin and investigate how different conditions affect the point at which they occur.
