1. ATMOSPHERE REVIEW DRILL: DESPITE LAWS PASSED TO REDUCE AIR POLLUTION WHY DOES THE PROBLEM STILL EXIST? OBJECTIVE: SWBAT IDENTIFY KEY CONCEPTS OF THE ATMOSPHERE IN ORDER TO PREPARE FOR THE QUIZ. HW: STUDY

2. COMPOSITION OF THE ATMOSPHERE NITROGEN: 78% USED FOR GROWTH AND REPAIR OF CELLS OXYGEN: 21% USED TO BURN ENERGY OTHER GASES: 1% CARBON DIOXIDE: TRAPS HEAT METHANE: TRAPS HEAT

3. TRENDS IN THE ATMOSPHERE PRESSURE: WEIGHT OF THE ATMOSPHERE PUSHING DOWN ON EARTH. DENSITY: AMOUNT OF MATTER IN A GIVEN AMOUNT OF SPACE. AS ALTITUDE INCREASES BOTH PRESSURE AND DENSITY DECREASE. TEMPERATURE: DECREASES AND INCREASES ALTERNATELY. 3 SOURCES OF ATMOSPHERIC HEAT GROUND SUN OZONE LAYER

4. LAYERS OF THE ATMOSPHERE EXOSPHERE: SATELLITES ORBIT IN THIS LAYER THERMOSPHERE: CONTAINS IONOSPHERE THAT CAUSES AURORAS AND RADIO WAVES TO BOUNCE OFF MESOSPHERE: METEORS BURN UP IN THIS LAYER STRATOSPHERE: OZONE AND JET STREAM TROPOSPHERE: WEATHER OCCURS HERE
