| Question / Word | Answer / Definition |
|---|---|
| Greenhouse Effect | the process by which the atmosphere traps infrared rays over the Earth's surface |
| radiation | transfer of energy by waves moving through space |
| convection | transfer of heat through the movement of heated material |
| conduction | transfer of energy in which vibrating molecules pass heat along to other vibrating molecule through direct contact |
| humidity | amount of water vapor in the atmosphere |
| global warming | an increase in the temperature of Earth's lower atmosphere, caused in part by increased levels of CO2 and water vapor |
| evaporation | the process that changes a substance from a liquid toa gas at temperature below substance's boiling point |
| transpiration | the loss of water through the leaves of plants |
| cloud | a dense, visible mass of tiny water droplets or ice crystal suspeneded in the atmosphere |
| cold front | boundary formed where a cold air mass overtakes and lifts a warm air mass |
| warm front | boundary formed where a warm air mass overtakes and rises over a cold air mass |
| dew point | temperature to which air must be cooled to become saturated |
| condensation | process by which water vapor changes to a liquid water |
| What is Earth'c most common element in the atmosphere? | Oxygen |
| What could a liquid thermometer not work without? | a vacuum at the top of its tube |
| what does a sling psychrometer measure? | the dew point and relative humidity |
| Where do air masses develope their temperature and air pressure from? | their source regions |
| which is denser cold or warm air? | cold air |
| how do you name wind | from the direction it comes from |
| What do you need to make a cloud? | water vapor, falling temperature, and condensation nuclei |
| what is the percentage of relative humidity at it's dew point? | 100% |
| What is the only substance that can survive in all states in Earth's atmosphere? | water |
| What are weather scientists officially called? | meterologists |
| How much pressure presses down on you? | 14.7 per square inch |
| Cirrus clouds look like... | hair strands |
| stratus clouds look like... | a sheet |
| cumulus clouds look like... | lumpy pillows |
| what are the stages of the hydrologic cycle? | evaporation-condensation or transpiration-condensation |
| Which laych of the atmosphere holds all life on Earth? | Troposphere |
| What layer of the Earth's atmosphere contains ozone? | stratosphere What purpose does ozone serve? |
| How do clouds form? | The water vapor rises into the air and reaches a point where it freezes around condensation nuclei. |
| How is energy transferred form the sun to the earth's surface and through the troposphere? | by radiation |
| What two gases are most abundant in the atmosphere? | Nitrogen and Oxygen |
| How do winds form? | The warm air rises up and pushes the cold air down. Also cold air comes from the poles to meet warm air at the equator. |
| What type of weather would follow a warm front? | rain |
| What type of weather would follow a cold front? | short-lived violent storms or light precipitation |
| What tool measures atmospheric pressure? | barometer |
| A rising barometer indicates what type of weather? | rain |
| Why are you not crushed by the atmospheric pressure? | because equal pressure is inside us because of our pores and mouths etc. |
