The four mainlayers of theAtmosphereare classifiedaccording tochanges in:
Additional Info
How are the layers classified?

tropo = changing conditions1. We live in this layer
2. Weather occurs here
3. Thinnest Layer, contains 80% of the mass of the atmosphere.
4. Most dense layer5. Temperature decrease
with altitude

Strato= layered, spreading out.
1. Ozone Layer
2. 3 Oxygen Atoms- O3
3. Absorbs UV radiation- produces heat causes the top of this layer to be warmer
B. Stratosphere

1. Meso=Middle
2. Coldest Layer -120˚C at the top
3. Burns up Meteoroids you see as a shooting star.
C. Mesosphere

Thermo=Heat1. Very thin air. (very
little air) extremely low density
2. 1,500°C or higher, but feels cold due to low density. Too few particles collide with your body.
3. No Outer Limit
D. Thermosphere (Divided into 2 layers)

Ions= charged particles
1. Causes the Aurora Borealis (Northern Lights)
2. Bounce radio communications off this layer.
D1. Ionosphere

Exo=“outer”1. Outer most layer of
the thermosphere.2. Satellites orbit here.
ISS 205 mi, 400km
D2. Exosphere

1. Convert miles to km.2. Convert km to cm.3. Divide by 200,000 to
get your scale cm.4. Create your scale
model by following steps 4-7 on the scaling the atmosphere sheet.
