Do now 1. List the chemical composition of the atmosphere including percentages. 2. Connect air pressure and density. You can use a picture to help. Why do we care about the layers? • The different layers are essential to human survival. • We need to be aware of how our actions in the troposphere affect the other layers of the atmosphere. The Layers of the Atmosphere (They’re out of this world! Lol, get it? ) Layers of the atmosphere •All weather happens here •Air pressure is highest in this layer •Temperature goes down as you go higher The Troposphere •Lies next to the Earth’s surface •Densest atmospheric level (because gravity pushes down on it the most) •Almost all gases, pollution and life found here Layers of the atmosphere •Jets fly in the bottom of this layer •Air pressure is lower than troposphere •Temperature goes up as you go higher The Stratosphere •Air is very thin • There is almost no moisture in this layer so it’s very dry * inside the stratosphere * Contains ozone which absorbs sun rays and keeps us from overheating Layers of the atmosphere •Meteors or shooting stars burn up here •Air pressure is lower than stratosphere •This is the coldest layer of the atmosphere The Mesosphere • Coldest layer • As altitude increases , temperature decreases • Very windy Layers of the atmosphere •Auroras happen here •Air pressure is lower than mesosphere •Temperature goes up as you go higher The Thermosphere *Very high temperature (BUT IT IS NOT HOT). *This is because the particles are moving fast but do not touch. * Contains the ionosphere where electricity makes gases light up = The Northern and Southern Lights Layers of the atmosphere •Many satellites orbit here •Air pressure is lowest here •Temperature goes up as you go higher The Exosphere • This is outer space!!
