(Represented with a star) Jet Stream- fast flowing _________________________________. (Labeled with Line) -Located between Troposphere and ____________________________. Stratosphere- layer above the troposphere -Upper stratosphere contains a layer of gas called ________________________, which is a form of oxygen gas. (Represented with dots) -Important to living things because it filters out most of the ______________________ -Without ozone to protect us the sun’s UV radiation would destroy ____________ on Earth. Mesosphere- located above the stratosphere. -The _______________________ layer of the atmosphere. (Represented with an X) Thermosphere- the outermost layer of the atmosphere -The ______________________ layer of the atmosphere. -Experiences the greatest change in temperature. (Represented with a ) -Charged particles interact with free electrons causing light to be given off. -This is how we get the ____________________ _____________________.
