Answer to Question 1

ANS: T
The expansion of ice occurs when the hydrogen bonds become more rigid. In the space 27 molecules
of liquid water occupy, only 24 solid molecules would fit. This is what allows ice to float. Information
can be found in the section Water Has Unusual Thermal Characteristics

Answer to Question 2

ANS: B
Light penetrates to approximately 100 meters in most areas. In tropical regions, the photic zone can
reach up to 600 meters. Information can be found in the section Light Does Not Travel Far through the
Ocean.
