A thermometer is used to measure __________________.
Temperature
100
The constant movement of water from the Earth's surface to the atmosphere and back to the Earth's surface.
What is THE WATER CYCLE

A front is formed when __________________________.
One air mass moves another air mass.
200
A ____________ is an instrument that measures the amount of humidity in the air.
hygrometer
200
An "H" on a weather map means ________________.
High pressure
200
A _______________ is used to measure the direction of the wind.
Wind Vane
200
TRUE or FALSE. When two LARGE air masses (cold and warm) collide, the weather is less severe.
What is FALSE.
300
Describe what happens with a cold front.
A cold air mass moves in, rides up under the warm air mass, pushing it up violently. This causes cumulonimbus clouds to form, bringing bad weather.
300
If the meteorologist says there will be a high pressure tomorrow, what will the weather probably be like?
Sunny and dry
300
A ____________ is used to measure the speed of wind.
Anemometer
300
Name a weather instrument and tell what it's used for.
Answers will vary.
300
A person who studies weather is called a ________________.
Meteorologist
400
What happens when a warm front moves in?
A warm air mass slides up over a cold air mass bringing steady rain or snow.
400
What type of weather system is represented with a solid line and half circles?
Warm front
400
Early in the morning, it is cloudy. By the afternoon it is very sunny. You can conclude that the barometer is _______________. (falling/rising) Why?

What heats a puddle on the Earth and causes it to evaporate?
What is THE SUN
400
Describe the three types of clouds. (The way they look, location, and type of weather they bring)
Cumulus: white, puffy clouds that indicate fair weather. They are found at various locations in the atmosphere. Cirrus: thin, whispy clouds found very high in the atmosphere. They are made of ice crystals and indicate fair weather. However, they can mean there will be a change in the weather soon. Stratus: Thick, Low-lying grayish clouds that indicate light steady rain or snow.

If the wind is moving from the east to the west, which way is the wind vane pointing?
East
500
The area we live in is describe as having warm summers and cooler winters. The is an example of an area's _______________. (weather/climate)
Climate
500
When the humidity is high, it is (more, less) likely to rain? Explain your reasoning.
More likely. Humidity is the amount of water vapor in the air. The more water vapor you have in the air, the more likely it is to rain.
500
What is the difference between climate and weather?
Climate is a pattern of weather over a long period of time, whereas weather is the condition of the atmosphere at a certain place and time.
