The 4 Layers of Earth’s Atmosphere

Earth’s Atmosphere

Earth’s Atmosphere (draw line every 7 cm and cut-top sheet only!)

Earth’s Atmosphere Height NOT to scale! Let’s fix that Thermosphere 100-500 km Mesosphere Height NOT to scale! Let’s fix that 50-100 km Scale: 1cm=18km Stratosphere Height of Thermo= ____ ~22cm 15-50 km Height of Meso= _____ ~3cm Height of Strato= _____ ~2cm Height of Tropo= _____ ~1cm Troposphere 0-15 km Earth

Now shade the rest of each door Earth’s Atmosphere Thermosphere 100-500 km Mesosphere 50-100 km Now shade the rest of each door Stratosphere 15-50 km Troposphere 0-15 km Earth

Earth’s Atmosphere You finish the rest Thermosphere 100-500 km Mesosphere You finish the rest 50-100 km Stratosphere 15-50 km Lowest layer of the atmosphere Temp. decreases as altitude increases Contains 80% of the atmosphere’s total mass Almost all life forms are here
