Surfaces with higher albedo reflect more solar radiation, staying cooler, while surfaces with lower albedo absorb more heat.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Fresh Snow<\/strong> has the highest albedo, reflecting 80\u201390% of incoming sunlight. Its bright white surface is highly reflective, making it the most efficient at bouncing back solar radiation.<\/li>\n\n\n\n<li><strong>Tops of Thick Clouds<\/strong> also have a high albedo, around 70\u201390%. Clouds play a major role in Earth&#8217;s energy balance by reflecting a significant portion of sunlight back into space.<\/li>\n\n\n\n<li><strong>Light-Colored Roofs<\/strong> vary depending on materials and coatings, but generally reflect 40\u201370% of sunlight. White or reflective roofing materials help keep buildings cooler.<\/li>\n\n\n\n<li><strong>Grass<\/strong> has a moderate albedo, usually between 15\u201325%. This means it absorbs more sunlight than snow or clouds but still reflects more than darker surfaces like forests or asphalt.<\/li>\n\n\n\n<li><strong>Forests<\/strong> have a lower albedo, around 10\u201320%, because tree canopies absorb a significant amount of solar energy. The dense leaves and darker surfaces make forests effective heat absorbers.<\/li>\n\n\n\n<li><strong>Asphalt<\/strong> has the lowest albedo, typically between 5\u201310%. Its dark color absorbs most of the incoming solar radiation, making it one of the hottest surfaces in urban areas, contributing to the urban heat island effect.<\/li>\n<\/ol>\n\n\n\n<p>Understanding albedo is crucial in climate science, as surfaces with lower albedo contribute to warming, while high-albedo surfaces help cool the environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rank the following surfaces from the highest albedo to the lowest albedo.
