(Q005) Which of the following statements is true?Group of answer choicesRoughly half of a floating block of ice lies below the surface of the water.Icebergs, by definition, are free-floating chunks of ice that are at least 6 m above water and at least 15 m long.Ice is denser than water.Tidewater glaciers are glaciers that experience movement due to the tides.

(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.

(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.

Three blocks, labeled A, B, and C, are floating in water as shown in the drawing. Blocks A and B have the same mass and volume. Block C has the same volume, but is submerged to a greater depth than the other two blocks. Which one of the following statements concerning this situation is false?Group of answer choicesThe volume of water displaced by block C is greater than that displaced by block B.The buoyant force acting on block C is greater than that acting on block B.The buoyant force acting on block A is equal to that acting on block B.The volume of water displaced by block A is greater than that displaced by block B.
