Snow Metamorphism
ET Dry Metamorphism:
- reduces surface free energy to its stable state
- Depends mostly on radius of curvature
- Convex: positive; steeper convexity is higher radius, which can hold a higher vapor density over it
- Hollows: negative
- Vapor flows along gradient - from points to hollows
- Reduces surface to volume ratio, therefore density increases (fills pore spaces)
- Structural strength increases (builds bonds)
- Rounds the snow grains
