Sample Question 1
What is the fundamental structural difference between a slab avalanche and a loose snow avalanche?

Slab avalanches only occur during nighttime while loose snow avalanches occur during daylight

Slab avalanches always travel faster than loose snow avalanches on any slope

Slab avalanches start from a small point release and fan outward while loose avalanches release along a wide fracture line

A slab avalanche releases as a cohesive plate of snow along a weak layer interface while a loose snow avalanche initiates from a single point and fans outward progressively

Sample Question 2
What is the crown fracture of a slab avalanche?

The lowest deposit point where snow accumulates in the runout zone

The hard icy surface exposed after the avalanche has removed the overlying slab

The lateral edges on the sides of the avalanche path where the slab broke from stable snow

The sharp near-vertical wall at the top of the release zone where the snow fractured and separated from the stable overlying snowpack

Sample Question 3
Slab avalanches pose a greater burial and survival risk to backcountry travelers than loose snow avalanches because they release large volumes of dense cohesive snow simultaneously.
