Question

Which of the following is NOT listed as one of the four primary categories of snow avalanches formed by combining classifications?

• A. Dry Snow Direct Action Avalanche
• B. Wet Snow Delayed Action Avalanche
• C. Ice Snow Direct Action Avalanche
• D. Dry Snow Delayed Action Avalanche

Answer 1

Answer:

C. Ice Snow Direct Action Avalanche

Based on the previous notes, the four primary categories of snow avalanches are formed by combining "dry snow" and "wet snow" types with "direct action" and "delayed action" triggering mechanisms.

Therefore, Ice Snow Direct Action Avalanche is NOT listed as one of these four primary categories.

• Ice snow isn't a fundamental classification type for snow avalanches in this specific system, which focuses on the moisture content of the snow (dry vs. wet). While ice can be part of a debris avalanche, the classification in the notes is specific to snow.

• The four categories derived from the previous notes are:

  1. Dry Snow Direct Action Avalanche

  2. Dry Snow Delayed Action Avalanche

  3. Wet Snow Direct Action Avalanche

  4. Wet Snow Delayed Action Avalanche
