100

This is the mass of air surrounding a planet

What is atmosphere

100
These two gases make up the majority of Earth's atmosphere

Nitrogen and Oxygen

100

This is the force (or weight) applied over a unit of area

Pressure

100

Atmospheric Pressure changes with weather and also changes based on THIS - which is the height of an object or point in relation to sea level or ground level.

altitude

100
This is the transfer of heat energy by waves through air or empty space

radiation

200
Air is a mixture of this that surrounds the planet

gases

200

Nitrogen makes up this percentage of the atmosphere

78.8 percent

200

This is the pressure the atmosphere exerts on all objects within it. 

Atmospheric Pressure

200

gas molecules in the atmosphere between more or less dense this near Earth's surface

more

200

This is the transfer of heat energy from molecule to molecule by contact

Conduction

300

Earth's atmosphere forms a layer of protection between Earth and this

space

300

Oxygen makes up this percentage of the atmosphere

20.95%

300

Meterologists use changes in atomospheric pressure to help predict this: 

changing weather

300

gas molecules become less dense as the altitude does this. 

increases

300

This is the transfer of heat energy through a liquid or gas by currents

Convection

400

True or False:   Cold air can contain more water vapor than warm air

False

400

These two gases in our atmosphere are essential for life: 

oxygen and carbon dioxide

400

1 atmosphere of pressure (ATM) is the average ATM at this location

sea level

400

The can in our experiment last week crushed because the atmospheric pressure on the inside was (greater/smaller) than the atmospheric pressure on the outside. 

smaller

400

This is energy that is transferred as a consquence of temperature differences

Heat

500

Name two ways Earth's atmosphere protects the planet.

sheilds Earth's surface from meteoroids and other falling debris; protexts from high energy radiation from space and sun's harmful rays; keeps Earth's temperature in a narrow range; allows sound waves to vibrate so that we hear birds, people, etc. 

500
This gas helps regulate the temperature of the Earth as well as provides the means by which plants can synthesise their own food.

carbon dioxide

500

At sea level, the atmosphere exerts an average of this amount of pounds on every square inch it touches

14.7 pounds

500
The higher you go , there are less of these - which causes there to be lower atmospheric air pressure

air molecules

500

This is the measure of the energy of random motion in a substance's molecules.
