Pbs Learning Media: Antarctic Ice Movement: Part I
This video segment [3:33] adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.
PBS
Pbs Learning Media: Antarctic Ice Movement: Part Ii
Within Antarctic ice sheets are fast-moving streams of ice. This video segment [5:15] adapted from NOVA hypothesizes about how ice streams are the result of warming at the end of the last ice age.
