weight of the colomn of air, sea level, barometer, Mercury
All weather moves...
west to east
Why do the temperatures in the thermosphere get warmer with increasing altitude?
Because the molecules are absorbing heat.
What is the warm ocean current that flows along the eastern USA coast?
Gulf stream
What are cold fronts?
They can be wet cold front (snow/ice), or dry cold front, (cold sunny).
What is the Earth's surface primarily made of?
78% Nitrogen and 20.9% Oxygen
What is a sea breeze?
A breeze blowing toward the land from the sea, especially during the day owing to the relative warmth of the land.
What instruments do scientist use to measure air pressure?
Barometer
Why do the temperatures in the mesosphere get colder with increasing altitude?
Because of the reduced molecular density and because the molecules grow farther apart and can't rub against each other to produce heat as they increase in altitude.
How does wind exist on Earth?
Because the Earth is an Oblate Spheroid and because of its 3D shape it does not heat equally in all places. This unequal heating and cooling cause air to move is what we call wind.
What is between 23.5 degree North and 23.5 degree South?
Tropics
What are the two most important heat-absorbing gases in the lower atmosphere?
Carbon-Dioxide and Water Vapor
Most of the US tornadoes occur in the BLANK part of the US
Central
What type of molecules damage the ozone layer?
Chlorofluorcarbons
What man-made pollutant is capable of destroying ozone molecules?
Chlorofluorocarbons, CFC
Which way does High Pressure rotate?
Clockwise
What is more dense? Hot or Cold air? Why?
Cold air, because its greater molecular density
Which way does Low Pressure rotate?
Counter-Clockwise
Where on Earth would you find the warmest and most moist air? Will it rise or fall? Why?
Equator, rise, because when air heats up molecules get farther apart.
What is the highest layer of the atmosphere?
Exosphere
Where are orbiting satellites found?
Exosphere
Which layer of the atmosphere has the coldest temperatures?
Exosphere
Is the following sentence true or false? Atmospheric pressure increases with height.
False, Atmospheric pressure decreases with increased height.
The boundry between two different air masses is called a BLANK
Front
The spinning of the Earth which produces the Coriolis Effect causes these to form?
Global Wind Belts
What could be the effect of an increase to the greenhouse effect?
Global-Warming
How does the temperature in the mesosphere change with increasing altitude?
It gets colder.
How does temperature change within the stratosphere (increases or decreases with increasing altitude)?
It gets warmer because of the ozone
What is a stationary front?
It is when a cold front and a warm front collide and it rains for several days
What is an Occluded front?
It is when a cold front overtakes a warm front, both moving in the same direction. They are vary rare.
What type of weather does High Pressure bring?
It produces fair and sunny weather.
Why is the ozone layer crucial to life on Earth?
It protects us from UV radiation
Where does the US sit?
It sits in the Westerlies.
What happens to temperature in the tropopause?
It's where the Troposphere ends, you're at the coldest point in the Troposphere.
High Pressure always flows to...
Low Pressure
The higher the elevation the BLANK the air pressure
Lower
What is the 3rd layer of the atmosphere (from the ground)?
Mesosphere
Where do meteors burn up?
Mesosphere
What gas is the largest component of the atmosphere?
Nitrogen.
How does the Ozone form?
O2 molecules are bombarded with cosmic rays (UV radiation) and seperate into O1 and O2 and combine together to create O3
What is between 66.5 degrees to 90 degrees North and South?
Polar Zone
What climate zones in Earth divided up by?
Polar, Temperate, and Tropical
If warm air is less dense than cold air then warm air will BLANK and cold air will BLANK, this circular motion sets up a BLANK
Rise, sink, convection cycle
Where is air pressure the greatest?
Sea level
The Earth heats unevenly because of its BLANK
Shape (oblate spheroid)
Something with a High Specific Heat will heat up BLANK and cool down BLANK
Slowly, slowly
What type of weather does Low Pressure bring?
Stormy weather, (warm or cold)
What is the 2nd layer of the atmosphere (from the ground)?
Stratosphere
Which layer contains the ozone layer?
Stratosphere
Where do most commercial airline pilots like to fly in the atmosphere? Why?
Stratosphere, the air is thin and less dense
What is between 23.5 degree to 66.5 degree North and South?
Temperate Zone
What causes the wind belts to remain so constant?
The Coriolis Effect
What is the lowest layer of the atmosphere?
Troposphere
Which layer contains clouds, wind, rain, snow, and most weather patterns?
Troposphere
Which layer do humans live in?
Troposphere
This caues Earth to have seasons.
The axial tilt. (23.5 degrees)
What is the tropopause?
The boundry layer between the Troposphere and Stratosphere.
Which layer is the densest?
Troposphere
Which layer of the atmosphere has the hottest temperatures?
Troposphere
Which layer of the atmosphere is closest to Earth?
Troposphere
What are the 5 layers of the Earth's Atmosphere? (Starting at the Earth's surface going up)
Troposphere Stratosphere Mesosphere Thermosphere Exosphere
Coastal Climates never gets to cold because...
Their distance from large bodies of water
Which layer contains the ionosphere?
Thermosphere
Which layer do space crafts fly?
Thermosphere
What are warm fronts?
They are weak fronts that usually bring rain.
How are ozone molecules different from oxygen molecules?
They both have different chemical formulas. Ozone= O3 Oxygen= O2
