Substitute
(d)
The reason for the difference in the rate of movement of the glacial ice in the centre and along the sides.
(d)
Answer to Problem 1GST
The frictional drags causes the glacial ice to flow at a slower rate along the sides whereas the central part is devoid of friction and can move at a faster rate.
Explanation of Solution
During the movement of glacial ice, the movement occurs both internally and externally. The frictional drag affects the external motion of the ice and it is more along the sides and bottom of the glacier.
The central part of the glacier escapes from the friction. This causes the central part of the glacial ice to advance forward at a faster rate than those along the sides, thus bringing difference in the rate of movement in the centre and along the sides of the glacier.
