The annual freezing and thawing of ice is a major factor on the regulation of temperatures on Earth. Indicate whether the statement is true or false
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.
