Why is it often colder on cloudy summer days?(

More sunlight is transmitted than reflected by the white upper surface of clouds.

More sunlight is reflected than transmitted by the white upper surface of clouds.

More sunlight is absorbed than transmitted by the dark lower layer of clouds.

More sunlight is reflected than transmitted by the white upper surface of clouds.

The correct answer is:

More sunlight is reflected than transmitted by the white upper surface of clouds.

The correct answer to the question is: "More sunlight is reflected than transmitted by the white upper surface of clouds."

When sunlight passes through clouds, it interacts with the water droplets or ice crystals that make up the cloud. Clouds appear white because they reflect most of the sunlight that hits them. Since the upper surface of clouds is white, it reflects a significant portion of the sunlight that reaches it.

On cloudy summer days, when the sun is higher in the sky, the sunlight has to pass through a thicker layer of cloud. This means that more sunlight is reflected back into space, and less of it reaches the Earth's surface. As a result, the amount of solar radiation that reaches the surface is reduced, causing the temperature to be lower compared to clear, sunny days.
