Why do scientists use weather maps?
They are able to predict weather patterns.

The atmosphere acts like the glass of a greenhouse. It traps heat near Earth’s surface. What is this the definition of?
The Greenhouse Effect
200
a large body of air with the same temperature and moisture content throughout depending on the area over which it formed
air mass
200
ozone layer and where airplanes fly long distances
stratosphere
200
Used to measure air pressure. It continuously records changes in air pressure using a rotating-drum
barometer
200
What does this symbol indicate on a weather map?
warm front
200
What is humidity?
The amount of water vapor in the air
300
Where two masses meet to form a border and where weather happens
Front
300
the coldest layer of the atmosphere
mesosphere
300
Used to measure humidity. Humidity is the amount of water vapor in the air

Temperature and moisture are used to describe what?
Air masses
400
All particles of air pressing down on the surface.
air pressure
400
top layer, hottest layer, lowest air pressure
thermosphere
400
Used to measure wind speed
anemometer
400
What do the H and L symbols on the map represent? 
High and low air pressure
400
What kind of air pressure does cold air have?
cold air has high air pressure
500
when a front stops moving and can stay in one place for several days
stationary front
500
List the layers of the atmosphere in order from the top layer to the closest layer to Earth
thermosphere, mesosphere, stratosphere, and troposphere
500
What is a wind vane? How does it work?
Used to measure wind direction. It has a tail and an arrow to show what direction the wind is blowing(north, south, east, west)
500
What weather occurs when there is a cold front? A warm front?
Warm front- rain and rise in temperature
Cold front- Weather cools, rain, thunderstorms, or snow occur
500
Dallas, Texas is warm and dry. A weather map shows a stationary front is near. What will the weather be like tomorrow? Why?
The weather will stay warm and dry because a stationary front means the weather does not change quickly. It stays the same.
