Answer to Question 1ANS: F
The mixed layer is subjected to various current and weather conditions that can have influential effects
on the water in this layer. The deep zone is the most stable layer in terms of temperature and density. It
contains cold, stable water. This layer comprises 80 of all ocean water. Information can be found in
the section Surface Water Moderates Global Temperature.
Answer to Question 2ANS: T
The dissolved solids and gases lower seawater's latent heat by approximately 4. The solids are able
to lower the freezing point because it is difficult for water molecules to form the necessary lattice
pattern of a solid. Information can be found in the section Water Has Unusual Thermal
Characteristics.
