The video tutorial explains the classification of avalanches, focusing on two main types: slab avalanches and loose snow avalanches. Slab avalanches occur when a cohesive layer of snow breaks away and slides down a slope, posing significant danger due to their speed and volume. Loose snow avalanches, or point release avalanches, start at a single point and create a fan-shaped path as they move downhill. These are generally smaller and less destructive but still pose risks to those on the mountain.

What is the primary basis for classifying avalanches?

• Their size

• Their location

• Their color

• Their type

Which type of avalanche involves a cohesive layer of snow breaking away?

• Ice avalanche

• Rock avalanche

• Loose snow avalanche

• Slab avalanche

Why are slab avalanches considered the most dangerous?

• They are unpredictable

• They are difficult to detect

• They release a large volume of snow at once

• They occur frequently

What is another name for loose snow avalanches?

• Point release avalanches

• Ice avalanches

• Rock avalanches

• Slab avalanches

What shape path do loose snow avalanches create as they move downhill?

• Circular

• Rectangular

• Fan-shaped

• Triangular
