Question

Quizplus · Accepted Answer

Earth's albedo is the fraction of incoming solar radiation that is reflected by Earth's surface and atmosphere. If Earth's albedo were greater than 0.39 (which is the current average), it would reflect more of the incoming solar radiation back into space, resulting in less energy being absorbed by Earth. This would lead to a colder temperature as less radiant energy would be emitted by Earth.
