 What happens to the air particles and the air pressure when you go higher up a mountain? | Air particles are further apart and the air pressure gets lower. The reason for this change is due to the cooling of the temperature. |
| How does a wind vein work? How do you know which direction the wind is blowing? | The wind vein shows the direction of the wind. The arrow points into the wind, if the arrow points south then wind is coming from the south. |
| Describe why a mist forms above the spout of a teakettle that contains boiling water. | It becomes water vapor and condenses when it meets colder air. |
| What is the purpose of an anemometer? | It determines the wind speed. |
| Why would someone who lives in a hot, humid place complain more of feeling hot than a person who lives in a hot, dry place? | Hot air contains a great deal of water vapor, so the sweat on anyones skin cannot evaporate quickly which makes you feel hotter. |
| When there is a greater difference in the air pressure between two places, what happens? | When there is a greater difference in the air pressure b/t two places then there will be strong winds. |
| The water cycle involves condensation of water and something else with water. What is the other part. | Water Vapor, Condensation, Evaporation and Precipitation are the other parts of the water cycle |
| What is a wind that is 120mph on the Beaufort called? | Hurricane |
| Condensation | The change of state from a gas to a liquid |
| Barometer | A device used to measure air pressure |
| Rain Gauge | A device for measuring precipitation |
| Relative Humility | The amount of water vapor present in the air at a given temperature compared to the maximum amount that the air can hold |
| Wind Vane | A device often shaped like an arrow used to show the direction of the wind. |
| Air Pressure | The push of the air in all directions against its surroundings. |
| Windsock | A device used to show wind direction. |
| Anemometer | A device used to measure the spread of the wind. |
| High-Pressure area | An area of higher air pressure than that of the surrounding air. |
