Question

predict what would happen if earths atmosphere became cloudy all the time.

more clouds would reflect more solar radiation, so the atmosphere would heat up.

more clouds would reflect less solar radiation, so the atmosphere would heat up.

more clouds would reflect more solar radiation, so the atmosphere would cool down.

more clouds would reflect less solar radiation, so the atmosphere would cool down.

solar radiation
diagram showing sun, clouds, trees, and percentages: 20% reflected by clouds, 6% reflected by atmosphere, 4% reflected from surface, 19% absorbed by atmosphere and clouds, 51% absorbed by surface

Explanation:

Clouds have a high albedo, meaning they reflect solar radiation. If Earth's atmosphere is always cloudy, more solar radiation will be reflected back. Less solar radiation being absorbed by the Earth - atmosphere system will lead to the atmosphere cooling down. So the correct statement is "More clouds would reflect more solar radiation, so the atmosphere would cool down."

Answer:

More clouds would reflect more solar radiation, so the atmosphere would cool down.
