5a. The net gain is 0.15km³/year (0.2 km
accumulated-0.05 ablated). This equals 15km³ in 100 years.
5b. In 100 years, the glacier volume will
increase by 15% to 115km³. (The original volume of the
glacier is 100km x 5km x 0.2km, or 100km³.)
6a. The net loss is now 0.15km³/year
(0.05 accumulated-0.2 ablated). This equals -0.15km or 15km³
in 100 years. At this rate the glacier will be completely melted
in 666.66 years (100km³/0.15km³/year = 666.7 years).
