100
This is when liquid water turns into water vapor and rises when heated by the sun.
What is evaporation?
100
In this process water vapor is cooled and condenses; water droplets clump around dust and other particles in the air.
What is how a cloud forms?
100
This is the movement of air in the atmosphere.
What is a convection current?
100
This front is represented on weather maps by semi-circles on a line.
What is a warm front?
100
This tool measures temperature.
What is a thermometer?
200
This is when water vapor is cooled and turned back into water droplets that condense and form a cloud.
What is condensation?
200
This is a form of cloud that is white and puffy and occurs when the weather is fair and sunny.
What is cumulus?
200
Movement in this layer of the atmosphere causes weather.
What is the troposphere?
200
This front is represented on weather maps by triangles on a line.
What is a cold front?
200

This tool measures wind direction.

What is a weather vane?

300
This is when air cools causing water droplets to get heavier and fall back to earth as rain, snow, sleet, or hail.
What is precipitation?
300
This form of cloud is high, wispy and made of ice crystals. It occurs in fair weather.
What is cirrus?
300
When on a mountain, air pressure is more, true or false?
What is false?
300
This front often brings light, steady rain and winds, fog, and stratus clouds.
What is a warm front?
300
This tool measures moisture, or humidity.
What is a hygrometer?
400
This is the essential part of the water cycle that heats water and turns it into vapor.
What is the sun?
400
This type of cloud is spread out and blanket-like. It occurs in light rain or drizzle.
What is stratus?
400
Cloudy, overcast weather usually signals this type of air pressure (Opposite of high).
What is low air pressure?
400
This front often brings brief, heavy storms or thunderstorms and strong winds.
What is a cold front?
400
This tool measures air pressure.
What is a barometer?
500
These are two terms that describe precipitation that runs down a slope and water that has come off of the slope.
What are runoff and groundwater?
500
These are the three main types of clouds.
What are stratus, cumulus, and cirrus?
500
True or false: Warm air sinks while cold air rises.
What is false?
500
This front often brings calmer weather and steady rain for several days.
What is a stationary front?
500
This tool measures wind speed. A Beaufort scale does the same job.
What is an anemometer?
