Answer to Question 1

ANS: T
Despite the high heat capacity of solid ice, it is still approximately half of that of liquid water. The
melting and freezing of water releases and uses heat energy. This cyclical pattern in the poles is an
effective means of moderating temperatures on Earth. Information can be found in the section Surface
Water Moderates Global Temperature.



Answer to Question 2

ANS: T
Water is a polar molecule. Water's geometric formation causes the atoms of hydrogen to have a
partially positive charge and the oxygen to be partially negative. This allows the molecules to be
attracted to other polar molecules. If a substance is held together by the attraction of opposite forces,
water is able to pull it apart. Information can be found in the section The Water Molecule Is Held
Together by Chemical Bonds

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
