A form of oxygen composed of three oxygen atoms bonded together. Ozone in the lower atmosphere is a pollutant, but in the upper atmosphere protects life from ultraviolet radiation.

The lowermost layer of the atmosphere; temperature decreases with altitude here.

Layer just above the troposphere; temperatures increase with altitude because of the presence of ozone.

Means "middle"; the layer between the stratosphere and thermosphere where temperature decreases with altitude. This is the coldest layer.

An outer atmospheric layer where gases are extremely thinly distributed. It is also the hottest layer

The process in which energy moves from a location of higher temperature to a location of lower temperature as heat. The material does not move, just the heat.

The movement of material due to differences in temperature.

The movement of energy through empty space between objects by electromagnetic waves.

The trapping of heat by greenhouse gasses in the atmosphere; moderates temperatures.

The mixture of gases that surround the Earth

The two gases that 99 percent of Earth's atmosphere is composed of

One of the two layers farthest from the Earth. The auroras, beautiful night lights, can be seen near the poles are in this layer of the atmosphere

The outermost layer of the atmosphere before entering space. This is where satellites orbit our planet

This reaches from Earth's surface to about 370 miles into space. Each layer of this serves a specific and important purpose in maintaining life on Earth

Hydrogen, methane, helium, argon, and carbon dioxide make up the other 1% of Earth's atmosphere

Air temperature and air pressure

As you travel farther from the Earth, _________ and __________both change.

Airplanes fly in the lower part of this layer because they can stay above the weather. The ozone layer lies in the upper most part of this layer.

Layers of the Atmosphere

Term	Definition
Ozone	A form of oxygen composed of three oxygen atoms bonded together. Ozone in the lower atmosphere is a pollutant, but in the upper atmosphere protects life from ultraviolet radiation.
Troposphere	The lowermost layer of the atmosphere; temperature decreases with altitude here.
Stratosphere	Layer just above the troposphere; temperatures increase with altitude because of the presence of ozone.
Mesosphere	Means "middle"; the layer between the stratosphere and thermosphere where temperature decreases with altitude. This is the coldest layer.
Thermosphere	An outer atmospheric layer where gases are extremely thinly distributed. It is also the hottest layer
Conduction	The process in which energy moves from a location of higher temperature to a location of lower temperature as heat. The material does not move, just the heat.
Convection	The movement of material due to differences in temperature.
Radiation	The movement of energy through empty space between objects by electromagnetic waves.
Greenhouse Effect	The trapping of heat by greenhouse gasses in the atmosphere; moderates temperatures.
Atmosphere	The mixture of gases that surround the Earth
Nitrogen and Oxygen	The two gases that 99 percent of Earth's atmosphere is composed of
Thermosphere	One of the two layers farthest from the Earth. The auroras, beautiful night lights, can be seen near the poles are in this layer of the atmosphere
Exosphere	The outermost layer of the atmosphere before entering space. This is where satellites orbit our planet
Earth's atmosphere	This reaches from Earth's surface to about 370 miles into space. Each layer of this serves a specific and important purpose in maintaining life on Earth
Inert Gases	Hydrogen, methane, helium, argon, and carbon dioxide make up the other 1% of Earth's atmosphere
Air temperature and air pressure	As you travel farther from the Earth, _________ and __________both change.
Stratosphere	Airplanes fly in the lower part of this layer because they can stay above the weather. The ozone layer lies in the upper most part of this layer.
