Temperature Differences

The video tutorial explores how sunlight affects Earth's surface by conducting a lab experiment. Students create two mini environments using soil, sand, and rocks, and measure their temperatures. One environment is shaded to simulate cloud cover, while the other is exposed to a lamp representing sunlight. After 10 minutes, the temperature in the sunny environment rises more than in the shaded one. The experiment concludes that sunlight significantly warms surfaces, while shaded areas experience less heating.

How did the temperature change in the shaded mini habitat compared to the unshaded one?

What conclusions can be drawn about the sun's effect on Earth's surface based on the experiment?
