Question

Quizplus · Accepted Answer

An increase in cloud cover and a corresponding decrease in absorption of solar radiation is an example of a negative-feedback loop. As more clouds form and block incoming solar radiation, the temperature on the Earth's surface will cool, making it less likely for more clouds to form. This creates a self-regulating mechanism that stabilizes the Earth's climate, which is the hallmark of a negative feedback loop.
