(Q008) Identify the true statement.Group of answer choicesDuring glacial retreat, the rate of ice accumulation exceeds the rate of ablation.During glacial advance, the toe moves downslope for mountain glaciers and outward for continental glaciers.When the rate of ablation equals the rate of accumulation, the glacier retreats.The boundary between the zone of accumulation and the zone of ablation is called the terminus.

Which of the following processes occurs during glacial retreat?Group of answer choicesThe rate of accumulation exceeds the rate of sublimationIce flows back toward the origin of the glacierThe position of the glacier's toe (terminus) moves back toward the origin of the glacier, even though ice continues to flow toward the toeThe ice stops flowing and simply melts away

(Q003) Identify the true statement.Group of answer choicesParts of a glacier all move at the same rate.Polar glaciers move along a wet cushion of liquid at their base.Continental glaciers spread across the landscape laterally in response to their own weight.The uppermost layer of ice in a glacier moves by plastic deformation; the base, by brittle deformation.

(Q010) Identify the true statement.Group of answer choicesThe process by which icebergs break off of coastal glaciers is called surging.Narrow, steep-sided, deep inlets of seawater in glacial valleys are called fjords.Today, glaciers cover 30% of the land; in the ice age, they covered 70%.Pluvial lakes are lakes that form on the surface of a glacier.
