Layers of the Atmosphere
The lowest layer where weather occurs.
What is the troposphere?
Energy from the Sun that powers Earth’s climate.
What is solar radiation?
Short-term conditions of the atmosphere.
What is weather?
Northern Lights.
What is the Aurora Borealis?
Layer where most airplanes fly.
What is the stratosphere?
Contains the ozone layer; airplanes often fly here.
What is the stratosphere?
Radiation that can cause sunburn.
What is ultraviolet radiation?
Force exerted by the weight of air molecules.
What is air pressure?
Southern Lights.
What is the Aurora Australis?

What are meteors?
Coldest atmospheric layer.
What is the mesosphere?
Hottest layer with ionized gases; auroras occur.
What is the thermosphere?
Warming of Earth’s atmosphere due to gases trapping heat.
What is the greenhouse effect?
Blanket of gases surrounding Earth.
What is the atmosphere?
Region within the stratosphere that absorbs UV rays.
What is the ozone layer?
Outermost atmospheric layer.
What is the exosphere?
Outermost layer transitioning to space.
What is the exosphere?
The rate at which temperature changes with altitude.
What is the temperature gradient?
Region within the thermosphere that affects radio communication.
What is the ionosphere?
Lights caused by solar particles interacting with the atmosphere.
What are auroras?
Region of charged particles affecting communication.
