Under what conditions will the firn limit remain the same from year to year? Under what conditions
will it change? What happens if the firn limit moves upward year after year? What will be an ideal response?
The firn limit will remain the same if accumulation equals wastage. The firn limit will move up the
glacier if more snow is lost than accumulated in a year, and will move down the glacier if more snow
is accumulated than lost in a year. Eventually, a negative budget will result in a glacier becoming too
thin to maintain flow. It will be a stagnant glacier and eventually disappear.
