Question: During one day, melt from a glacier's surface causes an average surface lowering of 14 cm, as measured at stakes drilled into the glacier ice.

During one day, melt from a glacier's surface causes an average surface lowering of 14 cm, as measured at stakes drilled into the glacier ice.

a. Compute the volume of meltwater generated, assuming that the glacier has an area of 1.5 km2 and the density of glacier ice is 850 kg/m3 (hint: first calculate the mass of ice = mass of water produced, then calculate the volume of water corresponding to the calculated mass).(4 marks)

b. Assume that all of the meltwater drains through a sub-glacial outlet stream over a 24-hour period. Compute the average rate of outflow in m 3 /s.(4 marks)
