Radiation |
The direct transfer of energy by electromagnetic waves |
|

Infrared Radiation |
Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves. |
|
|
Ultraviolet Radiation |
Electromagnetic waves with wavelengths that are shorter than visible light but shorter than X-rays. |
|
|
Greenhouse Affect |
The process by which heat is trapped in the atmosphere by gases that form a "blanket" around Earth. |
|
|
Temperature |
The measure of how hot or cold an object is compared to a reference point. |
|
|
Thermal Energy |
The total energy of motion in the particles of a substance. |
|
|
Heat |
The transfer of thermal energy from one object to another because of a difference in temperature. |
|
|
Conduction |
The direct transfer of thermal energy from one substance to another that it is touching. |
|
|
Convection |
The transfer of thermal energy by the movement of a liquid. |
|
|
Wind |
The horizontal movement of air from an area of high pressure to an area of lower pressure. |
|
|
Anemometer |
An instrument used to measure wind speed. |
|
|
Sea Breeze |
The flow of cooler air from over an ocean or lake toward land. |
|
|
Land Breeze |
The flow of air from land to a body of water. |
|
|
Global Winds |
Winds that blow steadily from specific directions over long distances. |
|
|
Coriolis Affect |
The change that Earth's rotaion causes in the motion of objects and that explains how winds curve. |
|
|
Jet Stream |
Bands of high-speed winds about 10 kilometers above Earth's surface. |
|
|
Water Cycle |
The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation. |
|
|
Evaporation |
The process by which water molecules in liquid water escape into the air as water vapor. |
|
|
Humidity |
The amount of water vapor in a given volume of air. |
|
|
Relative Humidity |
The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a paticular temperature. |
|
|
Psychrometer |
An instrument used to measure relarive humidity. |
|
|
Condensation |
The process by which molecules of water vapor in the air become liquid water. |
|
|
Dew Point |
The temperature at which condensation begins. |
|
|
Precipitation |
Any form of water that falls from clouds and reaches Earth's surface. |
|
|
Drought |
Long periods of low precipitation. |
