Water Cycle

100

This is when liquid water turns into water vapor and rises when heated by the sun.

What is evaporation?

200

This is when water vapor is cooled and turned back into water droplets that condense and form a cloud.

What is condensation?

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?

400

This is the essential part of the water cycle that heats water and turns it into vapor.

What is the sun?

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?

Clouds

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?

200

This is a form of cloud that is white and puffy and occurs when the weather is fair and sunny.

What is cumulus?

300

This form of cloud is high, wispy and made of ice crystals. It occurs in fair weather.

What is cirrus?

400

This type of cloud is spread out and blanket-like. It occurs in light rain or drizzle.

What is stratus?

500

These are the four main types of clouds.

What are stratus, cumulus, and cirrus and cumulonimbus

Air Pressure

100

High pressure air masses bring what type of weather

What is fair

200

Low pressure air masses bring what type of weather

What is stormy weather and strong winds

300

What measures air pressure

What barameter

400

Atmospheric pressure is the force exerted by what

What is weight of the air above us.

500

True or false: Warm air sinks while cold air rises.

What is false?

Fronts

100

This front is represented on weather maps by semi-circles or half sun on a line.

What is a warm front?

200

This front is represented on weather maps by triangles on a line.

What is a cold front?

300

This front often brings light, steady rain and winds, fog, and stratus clouds.

What is a warm front?

400

This front often brings brief, heavy storms or thunderstorms and strong winds.

What is a cold front?

500

This front often brings calmer weather and steady rain for several days.

What is a stationary front?

Tools

100

This tool measures temperature.

What is a thermometer?

200

This tool measures air pressure.

What is a barometer?

300

This tool measures moisture, or humidity.

What is a hygrometer?

400

This tool measures air pressure.

What is a barometer?

500

This tool measures wind speed. A Beaufort scale does the same job.

What is an anemometer?
