C. it reflects radiation from the sun
Polar ice helps maintain global temperatures by reflecting a large amount of sunlight back into space. This reflects the sun's energy away from the Earth's surface, preventing it from being absorbed and warming the planet. The white surface of ice and snow has a high albedo, meaning it reflects a significant percentage of sunlight that hits it. This process helps to regulate the Earth's temperature and prevent it from rising too high.
