Earth's Atmosphere
| Question | Answer |
|---|---|
| atmosphere | a thin layer of gases surrounding Earth |
| water vapor | water in its gaseous form |
| troposphere | the atmospheric layer closest to Earth's surface |
| stratosphere | the atmospheric layer directly above the troposphere |
| ozone layer | the area of the stratosphere with a high concentration of ozone |
| ionosphere | a region within the mesosphere and thermosphere that contains ions |
| radiation | the transfer of energy by electromagnetic waves |
| conduction | the transfer of thermal energy by collisions between particles of matter |
| convection | the transfer of thermal energy by the movement of particles within matter |
| stability | describes whether circulating air motions will be strong or weak |
| temperature inversion | occurs in the troposphere when temperature increases as altitude increases |
| wind | the movement of air from areas of high pressure to areas of low pressure |
| trade winds | steady winds that flow from east to west between 30 degrees N latitude and 30 degrees S latitude |
| westerlies | steady winds that flow from west to east between latitudes 30 degrees N and 60 degrees N, and 30 degrees S and 60 degrees S |
| polar easterlies | cold winds that blow from east to west near the North Pole and South Pole |
| jet stream | a narrow band of high winds near the top of the troposphere |
| sea breeze | wind that blows from the sea to the land due to local temperature and pressure differences |
| land breeze | wind that blows from the land to the sea due to local temperature and pressure differences |
| air pollution | the contamination of air by harmful substances including gases and smoke |
| acid precipitation | when sulfur dioxide and nitrogen dioxides combine with moisture in the atmosphere and form precipitation that has a pH lower than that of normal rainwater |
| photochemical smog | air pollution that forms from the interaction between chemicals in the air and sunlight |
| particulate matter | a mixture of dust, acids, and other chemicals that can be hazardous to human health |
| mesosphere | middle layer of the atmosphere; meteors can burn up in this layer |
| thermosphere | fourth layer of the atmosphere; temperatures here are very hot |
| exosphere | outermost layer of the atmosphere; spacecraft travel in this layer |
