Question 3: Melting of the Greenland
ice sheet would produce 7.2 m of sea-level rise, and melting of
the ________ would produce

outright ("impoundment") at just under the volume of ________
agreed with a dam-building peak in the 1930s-1970s timespan.
Question 9: The two primary
influences are temperature (because the volume of water depends on temperature), and the mass of water locked up on land and
