Question

During a sunny afternoon, the sun suddenly seems much less bright than usual. The daylight seems much less intense, as if there is a dense cloud cover, but there’s no clouds in the sky. After about half an hour, everything seems normal again. Which claim about the temporary decrease in light can be supported by the evidence?

Answer 1

Answer:

D). A sudden change in temperature increased the density of the atmosphere.

Explanation:

The claim that can be made and supported with evidence regarding the temporary decrease in light would be 'a sudden change in temperature will increase the density of the atmosphere.' As the temperature increases, the molecules in the atmosphere begin to move fastly which causes a decrease in atmosphere density while it increases with the fall in temperature. As a result, the intensity of sunlight gets affected due to molecules being heavier and floating in the atmosphere. Thus, option D is the correct answer.
