1. Geography PowerPoint on Earths Systems and Climates Age Range: High School Educational Goals: Basic understanding of Greenhouse Effects Understand the relationship between solar energy and air pressure Understand the importance of satellites Understanding of different climate zones around the world

2. Abstract The information for this PowerPoint was taken from an AGS World Geography text book. The information provided in the book was difficult to understand and was not visually stimulating for students. I pulled important facts and details then added visuals. The PowerPoint also includes a hyperlink to help explain the Greenhouse Effect. This can be manipulated together as a class or individually. Upon completion, students can individually take a quiz provided on that link. The slides can also be used to help prepare students for the test. The information can be removed thus leaving only the visuals. This is especially helpful when describing different climate zones. By creating this PowerPoint, students are still able to use the text to answer section questions and they feel less overwhelmed by the information presented.

3. Chapter 3: The Earths Atmosphere and Climates

4. Global Energy Systems zTemperature is the measurement of heat in the atmosphere. zEveryday the suns rays reach the earth. xSome rays are reflected back to space. xSome are absorbed and changed into heat energy. zhttp://www.epa.gov/globalwarming/kids/global_ warming_version2.htmlhttp://www.epa.gov/globalwarming/kids/global_ warming_version2.html

5. The Greenhouse Effect zA greenhouse is a special house built to grow plants. zThe earth traps energy the same way.

6. Who receives solar energy? zAll of the earth receives solar energy. zThe equator receives more solar energy than the North and South poles. zHeat energy is shared through: ywinds yocean currents

7. Air Pressure zAir pressure creates the winds and ocean currents that allows energy to be shared. zLow pressure yair is warmed, expands, becomes lighter, rises ybrings unstable weather

8. Air Pressure zHigh pressure- ycold air dense (heavy) mostly clear, dry weather zAir pressure zones - y1. Equator low pressure 2. Subpolar low pressure y3. Subtropical high pressure 4. Polar high pressure

9. Air Pressure Zones z1. Equator low pressure z2. Subpolar low pressure z3. Subtropical high pressure z4. Polar high pressure

10. Satellites zThey collect and send back information about the earth.

11. 2 types of light zvisible light zinfrared light - detects heat in clouds, water, and land

12. Satellite Images

13. Satellite Importance zTracking weather yclouds, storms, oceans zEnvironment ychanges in vegetation (plants) ymoisture yvisible and infrared light yland surface yair pollution ypests (bugs) ymonitor human activity (growth of cities)

14. yburning of rainforests yforest fires ycrop (farm) damage ypaths of oil spills yanimal movement yground movement of earthquakes

15. World Climate Zones

16. Classifying Regions zLow Latitudes yhumid tropical ytropical savanna zDry/Semiarid ydesert ysteppe zMiddle Latitudes yMediterranean yhumid subtropical z Middle Latitude ymarine west coast yhumid continental z High Latitude ysubarctic ytundra yice cap z Highland

17. Low Latitudes zHumid Tropical yalong equator xSouth America xZaire Basin Africa xSoutheast Asia yweather patterns xwarm and rainy year round yVegetation xtropical rainforest

18. Low Latitudes zTropical Savanna ybetween humid tropics and deserts xAfrica xSouth America xCentral America xSouthern and Southeast Asia xAustralia yWeather xwarm all year xrainy and dry seasons yVegetation xtropical grassland with few trees

19. Dry / Semiarid zDesert ySaharan Africa ysouthwest Asia ycentral and western Australia ysouthwestern North America zWeather yArid (low rainfall) ytropics x- sunny and hot ymiddle latitudes xhuge temperature range

20. Dry / Semiarid zSteppe - ybordering deserts xnorthern and south Africa xinterior western North America xcentral and interior Asia and Australia xsouthern South America yWeather xsemiarid - a little rain xhot summers xcool winters xsimilar to desert temp yVegetation - xgrassland, few trees

21. Middle Latitudes zMediterranean ymiddle latitudes, west coast xsouthern Europe xsouthwest Asia xCalifornia xsouthwestern Australia xcentral Chile xsouthwestern South Africa yWeather xdry, sunny warm summers xmild, humid winters yVegetation xscrub, woodland, grassland

22. Middle Latitudes zHumid Subtropical yeast coasts in middle latitudes xsoutheastern United States xeastern Asia xcentral southern Europe xsoutheastern parts of South Africa and Australia yWeather xhot, humid summers xmild, humid winters xin path of hurricanes and typhoons yVegetation xmixed forest

23. Middle Latitudes zMarine West Coast yupper-middle latitudes, west coast xEurope and North America xNorth America xsouthwestern South America yWeather xcloudy, mild summers xcool, rainy winters xstrong ocean influence yVegetation xtemperate, evergreen forest

24. Middle Latitudes zHumid Continental yeast coasts and upper middle latitudes xnortheastern North America xnorthern and eastern Europe xnortheastern Asia yWeather x4 seasons xlong, cold winters xshort, warm summers xrain varies yVegetation xmixed forest

25. High Latitudes zSubarctic yhigh latitude of interior and east coasts xnorthern North America, Europe, and Asia yWeather xextreme temperatures long cold winters short warm summers very little rain yVegetation xnorthern evergreen forest

26. High Latitude zTundra yhigh latitude coasts xnorthern parts of North America, Europe, Asia xAntarctica xsubantarctica islands yWeather xcold all year long cold winters short cool summers little rain yVegetation xmoss, lichens, low shrubs, permafrost bogs in summer

27. High Latitude zIce Cap ypolar regions xAntarctica xGreenland xArctic Basin Islands yWeather xfreezing cold snow ice all year little rain temperature is not higher than freezing

28. Highland zHigh mountain regions ywestern North and South America yeastern Asia and Africa ysouthern and central Europe and Asia zWeather ydetermined by elevation xhigher - cooler xlower - similar to surroundings

29. Summary What did we learn? zGlobal Energy zGreenhouse Effect zsolar energy zair pressure zSatellites zWorld climate zones

30. Review Which statements is true? zWe learned there is not a real importance in understanding climates. zWe learned that many factors play a role in influencing climates such as; –ocean currents –wind –elevation –people –Earths surface –sun zWe learned global warming is not an important issue.
