Layers of the Atmosphere Troposphere Tropo means turning

Layers of the Atmosphere!

Troposphere • “Tropo” means turning or changing • This is where all weather occurs. • Anywhere from 9 km to 16 km above sea level. • Temperature goes from warm to cold as you increase in altitude.

Stratosphere • Strato means layer or spread out. • Contains the Ozone layer. • From 10 km to 50 km above sea level. • Planes often fly here. • Temperature goes up as you rise in altitude due to the ozone absorbing the suns heat.

Mesosphere • “Meso” means • Temperature goes middle and is the down as altitude middle layer of the goes up. atmosphere. • Starts at 50 km above sea level and ends at 80 km. • Protects the earth from meteoroids.

Thermosphere • “thermo” means heat. • As you increase in altitude, temperature • Temperatures reach up goes up. to 1, 800 degrees Celsius or 3, 272 degrees Fahrenheit. • You actually would not feel warm in thermosphere! • 80 km above sea level and has no definite end.

Ionosphere • Called ionosphere because suns energy heats molecules to become ions. • 80 km to 400 km in the atmosphere. • Known for causing aurora borealis. • Temperature goes up as you increase in altitude.

Exosphere • Second layer of thermosphere. • Extends from 400 km and extends into space. • Hottest of the layers. • Satellites orbit Earth in this layer. • Temperature increases as you increase altitude.
