LAYERS of the

Atmosphere-notes-

Troposphere(Changing) (ball)

• 0-7miles (0-12 km)• Weather• We live here!• Temp decreases

(every half mile= 6.5 C)• Tropopause=top boundary -60C ice (Changing) (break)

TROPOPAUSE

7mi

Oh my word…I dropped my chips

Stratosphere(layer) (ball)

• 7-30 miles (12-50 km)

• Ozone layer

• Airplanes fly here

• Temp increases

• Stratopause= top boundary (layer) (break)

7mi

30mi

Stratopause

Mesosphere(middle) (ball)

• 30-53 miles (50-80km)• Shooting stars (meteor trails)• Temp decreases (top= -90C)• Mesopause = Top boundary (middle)(break)

53mi

30mi

WHEEEE!!Mesopause

Thermosphere(temp) (ball)

• 53 miles and above ( 80 km +)

• Thin, No outer limit

• Temp increases (can not record)

• Has 2 SUBLAYERS:

1) Ionosphere

2) Exosphere

Ionosphere (ion) (ball)

• 1st Sublayer of the Thermosphere

• 53- 250 miles (80-550 km)

• Aurora borealis- (Northern lights) sun particles hit ions toproduce a light that glows

53mi

250mi

Awesome light show!!

Exosphere(outside) (ball)

• 2nd Sublayer of Thermosphere

• 250 miles+ (550km and up)

• Satellites

• TV and Radio Waves

• GPS systems

250mi

BEYOND Mom?Can you here

me?

If I move this a little, does that mess up the GPS system in cars?

Yes?.....OOPS!!!
