Document Summary
The ability of a system to function or be maintained at a certain rate/level. Avoidance of depletion of natural resources in order to maintain an ecological balance. According to the old view the environment is the natural world apart from human society. New view : humans exist within the environment and our interactions with the environment have consequences. Each sphere interacts with another and their parts interact with the system. Some of the main 4 systems also have subsystems: the atmosphere, the hydrosphere, the lithosphere, the biosphere. Thin blue region along the edge of the earth. Is a mixture of gas molecules, small solid and liquid suspended particles, and falling precipitation. Without the atmosphere the earth would not have lakes and oceans. Consists of fresh, salt, and frozen water (snow and ice) The region of snow and ice is known as the cryosphere. Includes all the rock and geologic material making up the planet; also includes the soil (pedosphere)
