Quick Bite: Albedo Comparison
The Earth has an average albedo of about 0.3, which means that Earth reflects an average of about one-third of the sunlight it receives back into space. The table below shows approximate albedo values for a variety of surfaces and materials. What do you notice? Based on this table, how do you think the average albedo of the Arctic compares to the average albedo of the entire Earth? What about the region where you live?
