• troposphere, stratosphere, mesosphere, thermosphere, exosphere
• troposphere, mesosphere, thermosphere, exosphere, stratosphere

Define atmosphere and give (3) three examples of what the atmosphere does for the earth.

• Atmosphere is a layer of gases that surround the earth. Protects and supports life   Absorbs energy from sun Protects life from high energy radiation and frigid vacuum of space Recycles water and other chemicals
• Atmosphere is a layer of clouds that surround the moon. Destroys life.   Releases energy from sun. Damages life from high energy radiation and frigid vacuum of space Destroys the water table by emitting harmful chemicals

The density of our atmosphere _____________ with an increase in altitude.

• Increases
• Gets greater
• Decreases
• Gets heavier

This traps heat and absorbs gases (carbon dioxide, methane..) and keeps the earth warm. Allowing heat to go back into space prevents Earth from becoming too warm

• A blanket

• The Greenhouse Effect

• Greenhouse Gases

• Mesosphere
