Weather Fronts #1
What is a weather front?
the boundary between two air masses
What is the water cycle?
What is recycling of the water
What tool is used to measure barometric pressure?
What is barometer
What happens to air pressure as you decrease in elevation?
It increases, goes up
What direction across the US do the air masses move?
What is from West to East
If trees are broken, roof is gone, electric power line is damaged, but the walls of a large building are still there, what tornado category is that?
EF3
How does a cold front form? Draw a diagram on your white board.
When a cold air mass pushes under a warm air mass, forcing the warm air mass to rise.
What do moring wet grass, coulds, mirror after a hot shower, and glass of cold diet coke in a hot summer day have in common?
What is condensation
What kind of weather does a low pressure system bring?
What is cloudy, rainy, and windy
What happens to the amount of oxygen molecules as altitude increases?
Fewer molecules
The Coriolis Effect is...
What is Diflection of the wind from the equator
What is created by a difference in air pressure?
Wind
What symbol is used to represent a stationary front? Draw on your white board.
line with triangles and half circles on opposite sides.
Use white board. Name steps of the water cycle in order including energy that starts. Include plants.
1. Sun warms up the water
2. Evaporation
3. Transpiration
4. Condensation
5. Precipitation
6. Runoff
7. Infiltration
Underground flow
What does "L" stand for?
What is Low pressure
What happens under a low pressure after a vapor has condensed
What is precipitation
Are air masses that form over land dry or moist?
Dry
How do you get a breeze at the shore during a night time? Draw a picture
Warm air rises from the ocean, goes up and toward the land, cools down, returns to the ocean, warms up again and creates the breeze
What kind of weather does a cold front bring?
Colder temperatures and precipitation
What forms when water vapor condenses in the atmosphere?
Clouds
What happens when air is warmed or heated by the sun?
It rises
If a high pressure system is moving in, what kind of weather would you expect?
What is a fair weather and sunny
How is the movement of a hurricane around the US affected by Coriolis Effect. Draw on your boards
Hurricanes are form at the equator and move to the west first, but then because of Coriolis Effect curve to the North East
What kind of front could create tornadoes?
Occluded front
What most important change is the weather front responsible for?
What is temperature
What part of the soil would have the most moisture?
What is Bottom or underground
Explain convection process as it applies to air. Draw a diagram on your white board.
What is warm air rises and condenses as it cools
The lower the pressure the higher the chance of ...
What is rain
How come second hurricane is never as strong as the first one?
1st one absorbed most of the energy from the ocean not leaving enough for the second hurricane to be the same strength as the 1st
How do land and ocean absorb energy differently?
Land takes in energy faster and releases it faster,
ocean takes more time to absorb the energy, but stores it longer.
