Scientists say that glaciers flow. What does this mean? Group of answer choices The ice is so brittle that it crumbles when shaken by the wind, and the pieces roll downhill. The ice moves slowly downhill, because it is so cold and dense that it sinks through the rocks beneath. The ice kicks back and watches the football game on TV. The ice spins slowly in circles, because of the Coriolis force from Earth’s rotation. The ice is almost warm enough to melt, and so the ice deforms slowly something like the rocks in the mantle or a chocolate bar in your pocket.
