What you’ll learn

  1. A line made by a balanceDefine a mountain snow line and distinguish seasonal snow from snow that survives the melt season.A snow line is a moving boundary where snowfall, melt, shade, wind, and terrain balance differently across a mountain.
  2. Altitude turns air colderExplain why rising elevation usually lowers air temperature and changes whether precipitation falls as rain or snow.Lower pressure lets rising air expand and cool, so elevation can turn the same storm from rain in a valley to snow on a summit.
  3. Latitude and mountain shape move itConnect snow-line height to latitude, moisture, slope aspect, wind, and local terrain rather than treating it as one fixed altitude.The snow line is lower toward the poles and on shaded, snowy slopes, but nearby faces can differ because mountains reshape weather and sunlight.
  4. A snow line is a climate recordUse snow lines to reason about seasons, glacier mass balance, water supply, and long-term environmental change.Snow lines rise and fall with weather and climate, and repeated observations turn a visible boundary into evidence about frozen water.

Questions this course answers

What does a perennial snow line describe?

Perennial snow survives through at least one melt season, so its lowest persistent elevation is a long-term climate clue.

Why does rising air usually cool?

A rising parcel encounters lower pressure, expands, and cools as it does work on its surroundings.

Why can two slopes at the same elevation have different snow lines?

Aspect, shelter, wind transport, snowfall, and local terrain can make snow survive on one slope but not another.

Why is one photograph not enough to prove a snow-line trend?

Comparable repeated observations are needed to separate short-lived weather from a longer climate pattern.
