Atmospheric Composition

Air pressure is the BLANK measured at BLANK with a BLANK that uses BLANK

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?
