The most important terrain factor for avalanche formation is slope steepness.

Question

Quizplus · Accepted Answer

Slope steepness is the most critical terrain factor in avalanche formation because it determines the amount of gravitational force on the snowpack. Steep slopes increase the likelihood of snow instability and failure, leading to a higher risk of avalanches. Other terrain factors, such as aspect, elevation, and terrain roughness, also contribute to avalanche formation, but slope steepness is the most significant.
