***DOUBLE JEOPARDY***
Define Weather.
The Day to Day variation (change) in the atmospheres condition locally.
What process forms clouds?
The water cycle
Define Climate
The year by year average variation (change) in the atmospheres condition over a LARGE AREA.
Define air mass and air front
Air mass: Air Masses are large bodies of air that have the same temperature and humidity (water vapor) throughout.
Air front: The boundary where different air masses meet/collide
Where are maritime and continental air masses formed?
Maritime are formed over water
Continental are formed over land
What you wear!
How many main cloud types are there? and how are they classified?
4, classified by altitude
**DOUBLE JEOPARDY***
True or false: Climate creates seasons.
TRUE
How are air masses characterized and what is this known as?
How are these air masses moved around?
Characterized by the region they form in, known as SOURCE.
Moved around by Prevailing winds: Wind that blows mainly in one direction.
**DOUBLE JEOPARDY***
What two words have to do with humidity? What two words have to do with temperature? When we discuss air masses.
Humidity words- Maritime and Continental
Temperature words- Tropical and Polar
Weather occurs over how much time?
in short period of time
What are the 2 most common storm clouds?
Who studies climate? What do they use? What do they use those for?
Studied by Climatologists
Use temperature and precipitation to….
Describe different climates
Define boundaries between climates
**DOUBLE JEOPARDY***
What word means HUMID/WET/MOIST and HOT/WARM air?
Maritime Tropical
Maritime Polar air masses form over...
Continental Tropical air masses form in..
(mP) cold water of the Northern Pacific and North Atlantic Oceans
(cT) the summer over dry and hot areas in Mexico, Arizona, etc.
In what layer of the atmosphere does weather happen?
The Troposphere
**DOUBLE JEOPARDY***
What do Cumulus and Status clouds look like?
Cumulus - Fluffy like a pile.
Stratus- Think and Spread out like a blanket
**DOUBLE JEOPARDY***
Tell me about the temperate zone.
Variety of Climates here!
Regions closer to oceans vs. Regions closer to large land masses.
What are some of the things that could happen due to global warming?
Melting polar ice, sea level rising, extreme weather events like hurricanes and tornadoes and animals displaced from their homes.
What is being modeled?
Cold air front
**DOUBLE JEOPARDY***
What are the main factors of weather?
Has FOUR MAIN FACTORS:
1.) Temperature
2.) Humidity
3.) Wind speed and Direction
4.) Air Pressure
What do Cirrus and Nimbus Clouds look like?
Cirrus- Think and Wispy (like a curl of hair)
Nimbus- Grey and Dark
Tell me about the polar zone
Polar Zone
Very cold here!
Two distinct subregions are found here
Ice Cap and Tundra
What word means DRY and HOT air?
Continental Tropical
**DOUBLE JEOPARDY***
How many types of air fronts are there? What are they called?
Cold Front
Warm Front
Stationary Front
Occluded Front
How much sea ice has disappeared in the last 30 years?
40%
**DOUBLE JEOPARDY***
What is being modeled?
Warm air front
What is being modeled?
Occluded Front
**DOUBLE JEOPARDY***
What word means DRY and COLD air?
Continental Polar
What happens when a tropical (warm) and a Polar (Cold) air masses collide to make an air front? Why?
They do NOT mix because Cold air is heavy, has high pressure, and high density and Warm air is light, has low pressure, and low density. Warm air rises and cold air sinks.
What are the 5 important lines of latitude?
Using the clues below, name the climate!
Very cold winters with at least 1 month averaging less than 27 F
Mild summers-Between 60 -70 F
Severe (Arctic) Climate
Tell me about the tropical zone
Tropical Zone
Warm all year
Only has two seasons: Wet season and Dry Season
Use the clues below to determine the climate!
Annual average temperature is 10 F
Dry, very little precipitation
Polar Climate
What is the greenhouse effect? Why is it important? What can we do to help stop this increase?
The greenhouse effect is when a layer of gases in the atmosphere absorbs heat from the Earth to keep it warm. It is important because without it, the Earth would be too cold to live on. We are adding greenhouse gases to the atmosphere, increasing the greenhouse effect and warming the planet too much.
