Answer 2

Answer:

The roofs of houses in hilly areas are black because black absorbs heat.

Explanation:

To keep themselves warm, the people would have painted the roof black.

Black absorbs heat because:

Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
