| Question | Answer |
|---|---|
| A process in which a substance is converted directly from a solid to a gas or from a gas to a solid without the intermediate liquid phase. (Example: snow to water vapor or water vapor to snow) | Sublimation |
| Process by which water that is absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, such as leaf pores. | Transpiration |
| Water that falls and penetrates into the ground. Factors affecting infiltration; amount of precipitation, soil characteristics, soil saturation, land cover, slope of the land, and evapotranspiration. | Infiltration |
| A large natural or artificial lake used as a source of water supply. | Reservoir |
| The envelope of gases surrounding the earth or another planet. | Atmosphere |
| Solid particles in the air, such as dust, salt, or ash. | Particulates |
| The area of the atmosphere that is closest to the Earth where most of the weather occurs. Air temperature decreases as altitude (height) decreases. | Troposphere |
| Second layer of the atmosphere where the temperature tends to increase with altitude. | Stratosphere |
| Third layer of the atmosphere where air temperature decreases with altitude and very little solar radiation is absorbed. | Mesosphere |
| Fourth layer of the atmosphere that has a very low density and absorbs a large amount of the Sun’s radiation so its temperature increases with height. | Thermosphere |
| Fifth and outermost layer of the atmosphere, this is the transitional Area between the atmosphere and space with no clear ending point. | Exosphere |
| Solar radiation that ionizes gas molecules to create a positively charged ion and one or more negatively charged electrons. | Ionosphere |
| Charged particles beyond the atmosphere; these particles are held in place by Earth's magnetic field. | Magnetosphere |
| Spectacular light display that occurs near the poles; the _________ is in the thermosphere. | Aurora |
| An unstable, poisonous form of oxygen having the chemical formula O3 . | Ozone |
| Is the pressure exerted on a surface by the weight of the atmosphere above the surface. Normally in mb (millibars) | Air Pressure |
| The amount of mass per unit volume of a substance. | Density |
| Is the amount of water vapor in the air. High _____________ increases the chances of clouds and precipitation. | Humidity |
