Identify the true statement. choose one: a. regions covered by glacial ice are termed periglacial environments. b. the antarctic ice sheet has been calving off huge icebergs over the last few decades. c. glaciers move by basal sliding as friction between the ice and its substrate increases. d. the expansion of ice sheets at the end of the pleistocene caused glacial rebound in northern canada.

All the given statements are true except regions covered by glacial ice are termed periglacial environments.

Explanation:

Periglacial environments are regions on the edges of the glaciers. These areas or environments are not covered with ice. There is permanent frost in these environments but ice cover is lacking.

The other statements are all true. Antarctica glaciers are carving off leading to loss of glaciers. Glaciers usually move because of frictional forces between ice and its substrate. Northern Canada is experiencing glacial rebound.
