| Question | Answer |
|---|---|
| What do you call air with the same temperature and moisture? | Air masses |
| The weight of air pressing on everything around it is called | Air pressure |
| What does a anemometer do? | Determines wind speed |
| What do you call a layer of invisible gas that wraps around the planet like a blanket? | Atmosphere |
| Description of the atmosphere in terms of wind, temperature, clouds and precipitation is called an | Atmospheric condition |
| What measures atmospheric pressure (air pressure)? | Barometer |
| What do you call wispy air weather clouds; rain or snow? | Cirrus clouds |
| What do you get when a cold air mass is cutting under a warm air mass and lifting it? | Cold Front |
| Cumulus clouds that have grown very tall; usually bringing severe storms are called | Cumulonimbus clouds |
| Fluffy clouds that can bring storms if they grow too tall; also known as fair weather clouds are called | Cumulus clouds |
| What do you call a boundary between air masses with different temperatures and water vapor content? | Front |
| A prediction of future weather is called a | Forecast |
| Big frozen raindrops which occur during severe thunderstorms; cold air turns a raindrop into a tiny chip of ice; violent winds push the drop back up into the cloud to be coated again and again with more layers of ice are called | Hail |
| Fair weather is usually found in areas where air pressure is high; clouds and precipitation are usually found in areas where air pressure is low | High and low air pressure |
| What do you call the amount of moisture in the air? | Humidity |
| A huge, slow-moving storm that is fueled by heat and energy from warm ocean waters. | Hurricane |
| Anemometer, thermometer, barometer, and rain gauge are examples of | Meteorological tools |
| What do you call a scientist who studies the weather? | Meteorologist |
| Which cloud is known as a rain cloud? | Nimbus |
| Rain, sleet, snow, and hail are all types of | Precipitation |
| When cloud droplets become too heavy to stay in the cloud they fall toward the Earth as liquid water known as ____ | Rain |
| What instrument is used to tell how much rain has fallen in an area? | Rain gauge |
| What do you call a falling snowflake that melts by passing through warm air, refreezes by passing through cold air and becomes a block of ice? | Sleet |
| What are tiny ice crystals that attract to each other as they fall toward the ground? | Snow |
| Smooth gray clouds that block sunlight; can bring light rain and drizzle are called | Stratus clouds |
| The measure of the amount of heat energy in the atmosphere is called | Temperature |
| A storm with thunder and lightning and typically also heavy rain or hail is called a | Thunderstorm |
| Dark funnel of strong winds that spiral upward is called a | Tornado |
| The condition of the atmosphere at a place for a short period of time is called | Weather |
| A map showing the state of the weather over a large area is called a | Weather map |
| Repeating weather is also known as | Weather patterns |
| A warm air mass rises up over a cold air mass; causes thunderstorms but usually just brings lots of clouds and then light rain and snow. This is called a | Warm front |
