Layers of the Atmosphere
• Cut out all pieces
• Glue the appropriate name to the correct layer of the
atmosphere
• Color the Earth
• While working, think about key facts for each layer
5 minutes
Tell me what you know about…
• Roll the dice
• We will go through each layer of the atmosphere
• If your table is rolled, as a group you need to “tell me what you
know about” the selected layer
Troposphere
• 8 km (poles) 16 km (equator)
• 80% of atmosphere’s mass
• Contains water
• Weather occurs here
• Temperature decreases with
altitude
• Tropopause: top of troposphere
Prevents cool air from mixing
with warm air from stratosphere
Stratosphere
• 16 km to 50 km
• Warm
• Temperature increases with
altitude
• Contains ozone layer
(absorbs UV radiation)
• Low pressure
Mesosphere
• 50 km to 80 km
• Can get as cold as -120ᵒF
• Temperature decreases with
altitude
• 99.9% of the atmosphere
below this layer
• Protect Earth from collisions
by meteors
Thermosphere
• 80 km to 640 km
• 2700ᵒF or more due to
absorbed radiation
• Temperature increases with
altitude
• Very thin air
• Molecules are far apart
– rarely collide
• Satellites orbit in this layer
ISN – Layers of the Atmosphere
• Page 54
• Glue pictures to the correct layer
• Glue the Earth on the bottom center of the page
• Fold and glue the atmosphere layers about 2 cm apart, starting
with the layer closest to the Earth
