Question

Quizplus · Accepted Answer

Positive feedback, such as the initial cooling of the earth's surface by volcanic aerosols leading to increased ice cover, can trigger a snowball Earth event. This is because as the ice cover increases, it reflects more sunlight back into space, which further cools the planet, leading to even more ice cover. This creates a positive feedback loop that can cause the entire planet to become covered in ice.
