• Tropo means “turning” or “changing”.

• Contains most of the atmosphere’s mass.

• The weather forms here.

• Planes, balloons, and birds fly here.

• Strato means “layer” or “spread out”.

• Contains the ozone layer.

• Second layer

• Ozone = a form of oxygen that contains three oxygen atoms in each molecule instead of two.

• Ozone converts the sun’s energy to heat, warming the Earth.

• Protects Earth from dangerous ultraviolet rays.

• Meso means “middle”.

• Protects Earth’s surface from being hit by meteoroids and other material from space by burning them up upon entry.

• Thermo means “heat”.• Hottest layer because

sunlight strikes it first. • Extends into space, no

outer limit.• Broken into two sub

layers: ionosphere and exosphere.

• Energy from the sun causes gas molecules to become electrically charged particles called ions.

• These ions strike atoms in our atmosphere causing the atoms to glow creating the Northern Lights.

• The outermost layer of the thermosphere.

• Extends into space.• Satellites orbit in this

layer.

1. Walk around the room. When your teacher prompts you, stop moving and freeze.

2. Whomever you are standing next to, share something you learned today about the layers of the atmosphere with them.

3. You cannot repeat the same idea.
