Question

What characteristics are associated with weakly-bonded snow layers?

1) Large grain size and low density
2) Small grain size and high density
3) Strong bonding between snow grains
4) High moisture content and compacted structure

Answer 1

Weakly-bonded snow layers are characterized by large grain size and low density, which contribute to the instability of the snowpack and are important factors in avalanche safety.

Step-by-step explanation:

Characteristics associated with weakly-bonded snow layers typically include a large grain size and low density. The snow in these layers is not bonded tightly, which means that the individual snow crystals can move relative to each other more easily, potentially leading to instability in the snowpack. These characteristics can significantly affect the stability of snow and are especially important in contexts such as avalanche safety. Comparatively, layers with small grain size, high density, strong bonding between snow grains, or a high moisture content and compacted structure are indicative of more stable snow.
