Answer to Question 1

Glaciers also slide over underlying surfaces by basal slip. Basil slip is facilitated by the presence of
meltwater, which reduces friction between the glacier and the surface over which it moves. Basal slip
is more important in valley glaciers because they can slide down a slope



Answer to Question 2

Glaciers move mostly by plastic flow. When accumulating ice and snow reach a critical thickness of
about 40 m, the stress on the ice at depth is great enough to cause plastic flow, a type of permanent
deformation, involving no fracturing. If a glacier is solidly frozen to the ground, as in many polar
environments, it will move only by plastic flow.
