Document Summary
This is the essence of human impact on the environment (affecting natural critical balances) 3 factors that have contributed to the creation of the earth"s environment: the earth is located at an intermediate distance from the sun. 15 degrees is the average temperature on earth: water: solid, liquid, gas, oxygen rich environment: because of life. Example: cars affect the atmosphere with exhaust, the lithosphere with roads, through the elimination of tops and hills and valleys. If you affect one of the physical spheres on earth you affect them all. Solar energy (exogenous) contributes majority of the energy to the earths surface. Geothermal energy (endogenous) contributes very miniscule amount of energy to the earths surface. Solar energy -> heat energy -> has an impact on the atmosphere and produces kinetic energy. Solar energy-> latent energy: turning water from liquid to gas, evaporation. Consists of the troposphere, stratosphere, mesosphere and thermosphere (ordered from closest to the surface to furthest)
