a)
The average yearly rate of ice advance in the centre of the glacier with reference to the given diagram.
a)
Answer to Problem 1GST
At an average, the ice advance in the centre of the glacier is about 115 meters per year.
Explanation of Solution
The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters. Therefore, in 8 years it travelled 920 meters.
b)
The speed in the centre of glacier per day.
b)
Answer to Problem 1GST
The speed of the centre of glacier per day is about 0.32 meters or 32 centimetres per day.
Explanation of Solution
The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters. Therefore, in 8 years it travelled 920 meters. Therefore, per year it travels 115 meters. A year constitutes of 365 days.
c)
The average rate at which ice advanced along the side of the glacier.
c)
Answer to Problem 1GST
The glacial ice moves at the rate of 40 meters per year and 10.95 centimetres or 0.10 meters per day, along the sides.
Explanation of Solution
The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters and at the sides of the glacier is plotted as 320 meters. A year constitutes of 365 days.
d)
The reason for the difference in the rate along the sides of glacier from its center.
d)
Answer to Problem 1GST
Due the operation of frictional force, the movement of the glacier gets slower at the sides of the glacier when compared to the centre.
Explanation of Solution
The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters and at the sides of the glacier is plotted as 320 meters.
Along the sides of the valley, there occurs the frictional force between the valley side and glacier apart from the bottom of the glacier.
