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 30 m i Stratopause

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

53mi 30 mi 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) 1 st Sublayer of the Thermosphere miles ( km) Aurora borealis- (Northern lights) sun particles hit ions to produce a light that glows

53 mi 250 mi Awesome light show!!

Go here to see Aurora Video

Exosphere (outside) (ball) 2 nd Sublayer of Thermosphere 250 miles+ (550km and up) Satellites TV and Radio Waves GPS systems

250 mi BEYOND Mom? Can you here me? If I move this a little, does that mess up the GPS system in cars? Yes?.....OOPS!!!

POP QUIZ: 1) How many MAIN layers are there in the atmosphere? 2) What “factor” is it that makes it a new layer? 3) label: a) numbers b) layers-(6) c) arrows – up or down 4) tell me where you find: a) n. lights b) people c) satellites d) weather e) mountains f) meteors g) ozone h) airplanes i) plants
