Question
1) The area where mass is lost on a glacier is known as the zone of _________
2) The general region where the zone of accumulation meets the zone of ablation is known as the
a. Zone of no accumulation
b. Equilibrium line
c. Equal area
d. All the above
3)Calculating the net gain or loss of a glacier is known as _______
4) The area where mass is added to the glacier is known as the zone of __________
5) Which of the following is not a way glaciers lose mass.
a. Snowfall
b. Evaporation
c. Melting
d. Calving
Explanation / Answer
1)- ABLATION = For the glaciers there is the process of the loss of the ices in the form of melting water due to the reception of the isolation of the sun. so this process is called as ablation and the region of the glacier is going through the ablation is known as the Ablation zone.
2)
Equilibrium line = As name suggest it is the junction of the zones of the accumulation of the glaciers where the ices are added due to the natural precipitation and the zones of the ablation it is the zone which passes throgh the losses of the ice due to insolation.
3)
Mass balance= It is the net change in the mass of the glaciers over a period of the time specially one year. It is the net difference in between the net accumulation and the net ablation.
If the net accumulation > net ablation = mass balance = positive
If the net accumulation < net ablation = mass balance = negative
4)
Accumulation= This is the zone where their is continuous adding up of the ice in the form of the snow from the precipitation over the glaciers. in this area the intensity of the insolation is low.
5)
a- Snowfall == Snowfall means it is a part of the precipitation which causes the addition of the ices in the form of snow to the glaciers so it is the causes of the accumulation not the ablation
