|
Definition
troposphere, about 9 miles high |
|
|
Term
airplanes fly in the ______ because why? |
|
Definition
fly in the tropopause because air in the stratosphere does not interact much with the troposphere so we don't want chemicals to get stuck in the strat. |
|
|
Term
Reason Temp increases as we move upward in the stratosphere |

|
Definition
meteorological term for "the notion of reflectivity." Every syrface on the planet has it. |
|
|
Term

|
Definition
high latitude locations undergoing a loss of albedo surfaces. |
|
|
Term
|
Definition
15-25% reflectivity- results in a lower temp on grass than on asphalt |
|
|
Term
|
Definition
30-60%. pure white sand has higher albedo than black sand. |
|
|
Term
major geomorphic beings on planet earth. |

|
Definition
|
|

|
Definition
7% convection 23% evaporation from oceans and earth's surface 17% lost by long wave radiation |
|
|
