Layers of the Atmosphere Divided depending on Temperature How many layers are there in the atmosphere? There are 5 layers, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere,

Layers of the Atmosphere Troposphere: - This is the layer we live in and the smallest layer Temperature decreases as altitude increases 140 to -76 degrees F. WHY? All weather happens here This is the ONLY layer living things can live in 8 miles above sea level

Layers of the Atmosphere Stratosphere: Temperature increases as altitude increases from -76 to 32 degrees F Ozone layer found here, volcanic particulates Weather Balloons 8-30 miles above the earth

Layers of the Atmosphere Mesosphere: - Temperature decreases to coldest point 32 to -130 degrees F. - Meteor Showers - 30-50 miles

Layers of the Atmosphere Thermosphere: - Temperature increases 2700 degrees F - Aurora borealis (Northern lights), International Space Station, Space Shuttle stay in this layer. - 50-120 miles from sea level

Layers of the Atmosphere Exosphere: - Temperature Increases to 5000 degrees F - Satellites orbit here - 120 miles + from sea level Meteorology - is the study of the earths atmosphere
