The upper stratum, which usually has the highest dissolved oxygen concentration and is characterized by a temperature gradient of less that 1°c per metre of depth, is the epilimnion (literally the “upon-lake” or the “upper lake”). This stratum contains more or less uniformly warm, circulating, and fairly turbulent water.
The earth’s surface contains many forms of snow and ice, including sea, lake, and river ice; snow cover; glaciers, ice caps, and ice sheets; and frozen ground. Climate change can dramatically alter the earth’s snow- and ice-covered areas because snow and ice can easily change between solid and liquid states in response to relatively minor.
