Weather Fronts #1
The boundary between two air masses is called this.
A front.
What is the condition of Earth’s atmosphere at a certain time and place?
Weather
What causes wind to blow towards the land from the ocean during the daytime in the summer?
The land is warmer so the air above it heats and rises. Cool air from over the ocean rushes in to take fill the empty space.
What fast moving band of air causes most weather systems above the US to move from west to east?
The jet stream
What step in the water cycle occurs when liquid water becomes a gas or vapor?
Evaporation
Marked with a blue line on a weather map, this is formed when a cold air mass pushes under a warm air mass, forcing the warm air mass to rise.
A cold front.
What is the measure of how hot or cold something is?
Temperature
cold, cloudy, rainy
What is created by a difference in air pressure?
Wind
What step in the water cycle occurs when water vapor cools and becomes liquid?
Condensation
What symbol is used to represent a stationary front?
line with blue triangles and red half circles.
What is the amount of water vapor in the air?
Humidity
If a high pressure system is moving in, what kind of weather would you expect?
sunny, warm
If the Jet Stream dips down lower than expected, how would the weather in North Carolina be affected?
Temperatures would be cooler than average.
What step in the water cycle is most closely linked to plants?
Transpiration
What kind of weather does an occluded front bring?
Strong winds and heavy rain.
What forms when water vapor condenses in the atmosphere?
Clouds
What happens when air is warmed or heated by the sun?
It rises
At night in the summer, the ocean temperature may be warmer than the temperature of the sand on the beach. How will this affect the local breeze?
Cirrus and Cumulus
Marked with a purple line on a weather map, this forms when a warm air mass gets caught between two cold air masses.
An occluded front.
What is used to measure air pressure?
Barometer
Where do areas of high pressure go?
to areas of low pressure.
Assuming latitude and elevation are the same, would you expect summer temperatures to be cooler in a town near the ocean or a town further inland? Why?
A town near the ocean because the water's cooler temperature would help to cool the land.
If you see a layer of clouds covering the entire sky and a light rain is falling, what type of cloud are you most likely seeing?
Nimbostratus
