B) specific heat
C) cloud cover
D) evaporation
The land surface cools off more rapidly at night than water does because
A) the amount of energy stored in the land is less than that stored in the water column
B) the energy is stored in a shallow layer near the surface of the land, and so it can be
radiated away faster
C) all of these
D) none of the above - land does not cool off more rapidly than water at night

biological systems?
