Answer:
polar zones are cold because they have lots of snow and ice on the ground.
Explanation:
the snow and ice is reflective so light from the sun is reflected back into space instead of turning into thermal energy(heat).
D. They do not produce electricity.
Passive solar heating is a technique where the sun's energy
is used for heating spaces. It does not generate electricity but can save substantial
electricity by making use of thermal mass. Materials that have a high density
such as concrete and bricks absorb and store electricity. Along with operable windows
and thermal chimneys, thermal mass is being
utilized to take advantage of sun exposure.
