Term | Definition |
---|---|
Convection | the transfer of heat by the movement of a mass or substances. It can only take place in fluids |
Conduction | the transfer of heat through matter by molecular activity. energy is transferred through collisions from one molecule to another |
Radiation | the transfer of energy (heat) through space by electromagnetic waves |
Ozone Layer | a molecule of oxygen containing 3 oxygen atoms; a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. in the stratosphere. |
ionosphere | a complex zone of ionized gases that coincide with the lower portion of the thermosphere |
Stratosphere | the layer of the atmosphere immediately above the troposphere, characterized by increasing temperatures with height, owing to the concentration of ozone |
Troposphere | the lowermost layer of the atmosphere. it is generally characterized by a decrease in temperature with height |
Thermosphere | the region of the atmosphere immediately above the mesosphere and characterized by increasing temperature due to absorption very short solar energy by oxygen |
Mesosphere | the layer of the atmosphere immediately above the stratosphere and characterized by decreasing temperate with height |
Environmental Lapse Rate | the rate of temperature decrease with increasing height in the troposphere |
Most Abundant Gases in Our Atmosphere | Nitrogen (78%), Oxygen (21%), Carbondioxide (.036%) |
Albedo | the reflectivity of a substance, usually expressed as a percentage of the incident radiation reflected |
does temperature increase or decrease in each layer as altitude increases | decrease |
