What is a front?
the boundary between two air masses
What is the condition of Earth’s atmosphere at a certain time and place?
Weather
When a high pressure system goes to a low pressure system. The greater the difference, creates a horizontal movement. What is this called?
Wind
What pressure system creates clear sunny skies
High Pressure system
What direction do the fronts move in?
In the direction the symbol is pointing.
a front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather
Warm front
What front: When a cold air mass pushes under a warm air mass, forcing the warm air mass to rise. This usually bring stormy weather and rain
cold front
What is the measure of how hot or cold something is?
Temperature
cold, cloudy, rainy
What letters shows low pressure and high pressure systems?
L and H
What kind of front involves 3 different air masses?
Occluded Front
What is created by a difference in air pressure?
Wind
What symbol represents occluded front?
Purple triangles and circles on a line
Overall weather in an area over a long period of time
Climate
What is the force of the atmosphere on the surface of the earth?
Air pressure
What causes difference of air pressure around earth?
warm air rises, cold air sinks
Are air masses that form over land dry or moist?
Dry
Draw the Warm front symbol
Red line with half circles
What kind of weather does a warm front bring?
maybe a little drizzle of rain followed by clear skies and warm
The study of weather is called
meteorology
What happens when air is warmed or heated by the sun? (hint: in evaporation)
It rises
If a high pressure system is moving in, what kind of weather would you expect?
sunny, warm
What kind of weather is associated with a cold front?
Thunderstorms, rain, storms
Draw the cold front symbol
What front: when a warm air mass and a cold air mass meet and no movement occurs
Stationary Front
What are the 5 influences that make up the weather
Air pressure, Wind, Precipitation/ clouds, tenperature, humidity
A huge body of air that has similar temperature, humidity, and air pressure at any given height
Air mass
The amount of water vapor in the air.
humidity
TRUE or FASLE Weather fronts usually cause clouds and precipitation
TRUE
Draw stationary front
Red circles and blue triangles on a line
