WebThe albedo of Earth’s surface varies from about 0.1 for the oceans to 0.6–0.9 for ice and clouds—meaning that clouds, snow, and ice are good radiation reflectors while liquid water is not. This is because clouds, snow, and ice have multiple layers that reflect radiation, whereas a body of water reflects only from its surface. WebJul 15, 2016 · Explanation: Albedo is the measure of the reflectivity of a material. A high albedo means it reflects a lot of light and a low albedo means it absorbs a lot of light. An …

WebFor example, the albedo for fresh snow can be as high as .87 (87% of incoming solar energy is reflected). When the portion of ocean and land that is covered by ice and snow increases, the increased area of high albedo can be a positive feedback that increases cooling and expands the area covered with ice WebThe albedo of a surface is a measure of its reflectivity to solar radiation (Paterson, 1994 ). If the albedo of a surface is high, more radiation will be reflected than if the albedo is low. Hence, the average albedo of the planet dictates the levels of solar radiation held and reflected at its surface. Fresh snow has a particularly high albedo. sunova koers

WebWhy are oceans able to absorb more of the Sun's heat energy than land? Oceans have a lower albedo than land and so absorb more of the incoming solar radiation. Ocean currents generally follow a pattern of moving away from the equator along the eastern coast of continents and toward the equator along the western coast of continents.
