| QuestionS | Answer |
|---|---|
| Atmosphere conditions may not last a very long time. They may change from hour to hour. | Weather |
| The characteristic conditions of an area over a long period of time. | Climate |
| What type of climate is caused by winds blowing over an ocean bringing mild climate conditions. | Marine climate |
| This gas makes up the majority of the Earth's atmosphere. | Nitrogen |
| Which layer of the atmosphere contains the ozone? | Stratosphere |
| The layer of the atmosphere where life exists. | Troposphere |
| The amount of water vapor in the air. | humidity |
| Sunlight travels to the earth in waves by which method? | Radiation |
| How is energy transferred when solids touch? | Conduction |
| Air pressure is the measure of the .... | force of air molecules pushing on an area. |
| Where is the greatest pressure found? | Sea level |
| Air at the top of a mountain is different from air at the bottom because... | There are fewer oxygen molecules at the top of a mountain. |
| What causes wind? | Differential heating of the earth. |
| Global winds are caused by... | unequeal heating of the Earth's surface at the poles and the equator. |
| How does the Coriolis effect influence global winds? | It causes the winds to curve to the right in the Northern Hemisphere. |
| This occurs every 3-7 years when trade winds weaken causing the Pacific Ocean to become warmer and bringing unusually heavy rains to the Southeastern U.S. | El Nino |
| The Atlantic Ocean current, originating in the Gulf of Mexico that influences weather on the northeastern coast of the U.S. and England. | Gulf Stream |
| Precipitation that freezes as it falls through cold air before it hits the ground. | Sleet |
| The relative humidity on a very comfortable day in Alabama. | The relative humidity is low. |
| Thin, white, feathery, high altitude clouds that contain ice crystals. | Cirrus |
| Layered clouds that produce steady, light precipitation. | Stratus |
| Puffy white clouds that are often in the sky during fair weather. | Cumulus |
| When water molecules change from a gas to a liquid. | Condensation |
| What type of precipitation falls when wind moves an ice crystal back up into a cloud several times before it falls to the ground? | Hail |
| The boundary between a cold air mass and a warm air mass. | Front |
| What type of front forms when a warm air mass pushes a cold air mass and slips over the cold air? | Warm front |
| What does "H" represent on a weather map? | High pressure |
| What type of weather would you expect to have if you "H" on a map? | Fair weather |
| Name the events that can occur during a severe thunderstorm. | Hail,lightning, heavy wind, and flooding. |
| A storm that develops when low pressure forms over the warm ocean water with winds blowing more than 74 MPH. | Hurricane |
| A violently rotating column of air stretching from a cloud to the ground that is often spun from a severe thunderstorm. | Tornado |
| Which instrument is used to measure wind direction? | Weather vane |
| Air pressure is measured using this instrument. | Barometer |
| If an air mass is cooled, will the air pressure decrease or increase? | Increase |
