MAP SKILLS

1. MAP SKILLS

2. DO NOW • GET OUT YOUR NOTES!  • Create 3 quiz questions!!

3. CHANGE YOUR PERSPECTIVE • http://www.tickld.com/t/464202/

4. WHERE ARE WE GOING?! • TODAY: Finish Carbon Footprint • MOVE ON TO MAPS  • Friday: Topographic Maps, Quiz 1 • Look back at your vocabulary sheet: check off the topics we have covered!

5. What is a map? • A representation of an area of land or sea showing physical features, cities, roads, etc. • Many different types!

6. Directions: You should know these!

7. Map Projections • Representation of the earth stretched out onto a flat map • Uses mathematical gridlines called latitude and longitude

8. Types of map projections Interrupted Projection Mercator Projection

9. latitude and longitude • Used to specify position on a globe/projection map!

10. KEY TERMS • LATITUDE • LONGITUDE • EQUATOR • PRIME MERIDIAN

11. Latitude vs. Longitude LATITUDE • coordinates that define the north-south position on the globe LONGITUDE • coordinates that define the west-east position on the globe

12. Major gridlines • EQUATOR • main line of latitude at 0 degrees • PRIME MERIDIAN • main line of longitude at 0degrees

13. hemispheres • Hemi- = half • -sphere = area • What major lines divide each?

14. LATITUDE AND LONGITUDE LINES FORM A GRID • The globe is divided into a grid system. • Latitude– specifies position north/south of the Equator. • Equator = 0 degrees latitude • + (positive) 1-90 abovethe Equator • -(negative) -1-90 belowthe Equator • THOUGHT QUESTION: What latitude is the North Pole? What latitude is the South Pole? How do you know? • Longitude-specifies position east/west of the Prime Meridian. • Prime Meridian = 0 degrees longitude • + (positive) 1-180 rightthe Prime Meridian • -(negative) -1-180 leftthe Prime Meridian

15. Think: What’s the difference between a Map and a Map projection? • Map • Graphic representation of an area; does not necessarily use latitude and longitude grids Map projection • Map that uses math-supported grids • All map projections are maps, but not all maps are map projections

16. Map or map projection?

17. Map or map projection?

18. Map or map projection?

19. RECAP: Where is the equator located? Do you know the exact coordinates? Have you ever used a GPS?!

21. DO NOW • What are lines of longitude also called? Name he line of longitude that separates the Eastern hemisphere from the Western hemisphere? • Describe how chunks of weathered rock (sediment) form a sedimentary rock. In your answer, include pressure, foliated and non-foliated. • Using either the globe or your cell phone, record the coordinates for Conway, NC [Check for Understanding Is NC North or South of the Equator? East or West of the Prime Meridian?]

22. TIME ZONES • What is a time zone? • Thought Question: Why do time zones exist? • Does the sun RISE and FALL at the same time in all places in the world? • Even today (and especially in ancient times, people measured noon by the position of the Sun directly overhead!)

23. UNITED STATES TIME ZONES • What are the 4 major US time zones? • Eastern • Central • Mountain • Pacific • Which one we do we live in?

24. WORLD MAPS • Be able to locate the 7 continents! • The 5 major oceans! • Which ocean is LARGEST?

25. WEATHER MAPS: ISOTHERMS • Isotherm: lines that connect areas of equal temperatures • Iso= equal • Therm= temperature (or heat)

26. WEATHER MAPS: ISOBARS • ISOBARS: lines that connect areas of equal pressure

27. WEATHER MAPS: PRESSURE SYSTEMS • High Pressure Systems • Low Pressure Systems • Air moves from ______ to ________pressure…. • Pressure systems spin: • __________ in the Southern Hemisphere • ________-____________ in the Northern Hemisphere • http://www.bom.gov.au/lam/Students_Teachers/pressure.shtml

28. QUIZ YOURSELF! • Identify areas of: • HIGH PRESSURE • LOW PRESSURE • FRONTS (cold, warm, stationary, occluded) • STATE THE WEATHER THAT IS GOING ON IN different regions of the United States! • http://www.weather.com/maps/maptype/currentweatherusnational/index_large.html

29. HIGH PRESSURE SYSTEM • Regions of SINKING air • Highs • Anti-cyclones • Fair weather and clear skies • http://www.bom.gov.au/lam/Students_Teachers/pressure.shtml

30. LOW PRESSURE SYSTEM • REGIONS of RISING AIR • Cyclonesor depressions • Clouds, rain, STRONG winds • WHY? Warm air RISES, COOLS, begins to form CLOUDS!

31. Water vapor and weather • How are water vapor and weather related? • ____________: amount of water vapor in the air compared to how much water vapor the air can possibly hold. • Clouds are made of water vapor that has ______________ to form droplets. • When those clouds get heavy enough, water falls to the Earth as _______________. • 2. _______ ___________: temperature at which water vapor condenses to form droplets (usually in the troposphere). • THOUGHT QUESTION: Why does air temperature dictate how much water vapor the air can hold?

32. WATER IS AN ENERGY AGENT • Ocean currents move heat from the Equator towards the Poles • Ocean currents are due to: • Surface – wind • Density – temperature, salinity

33. BIOME CLIMATES • CLIMATE: • Average weather over time (months, years) • Precipitation (and humidity) • Temperature • Let’s look at some graphs that will characterize climates for each BIOME!

34. NAME THat BIOME! • Lowest precipitation next to the desert! • Coldest temperatures year-round! • CHALLENGE: NAME ONE MORE FACT ABOUT THAT BIOME (plants, animals, adaptations)

35. NAME THAT BIOME! • CHALLENGE: NAME ONE MORE FACT ABOUT THAT BIOME (plants, animals, adaptations)

36. NAME that Biome! • CHALLENGE: NAME ONE MORE FACT ABOUT THAT BIOME (plants, animals, adaptations)

37. BIOME SUMMARY • COMPARE/CONTRAST ACTIVITY: • Compare: Desert and Tundra • Contrast: Rainforest and the Temperature Deciduous Forest
