The biggest concern with Global Warming is the impending Melting of the Ice Caps. As long as they are white and reflective, they are capable of reflecting heat and remaining frozen. As soon atmospheric temperatures rise, and the snow melts, the darker, more absorbant landscape under the snow is slowly revealed, which quickly increases the rate of heat absorption- meling the snow even faster. What do you call this very important "reflection of light/heat," in this case, by the snow. a The Greenhouse Effect b The Albedo Effect c The Butterfly Effect

The correct term for the "reflection of light/heat" by the snow in this case is the Albedo Effect. The Albedo Effect refers to the ability of a surface to reflect light, with a higher albedo indicating a greater reflection of light and heat.
