On the initiation of a snowball earth
WebSnowball Earth Albedo Effect. 867 Words4 Pages. The initiation of a Snowball Earth, involves a cooling mechanism in which an increase in the Earth’s coverage of snow and ice occurs. As mentioned previously, an increase in ice and snow coverage would result in an increase in the reflected fraction of solar radiation known as albedo.
