Map and globe skills

  1. 1. Map and Globe Skills Mr. Coltabaugh World Geography
  2. 2. Using Globes Globe is a scale model of the Earth Represents size, shape, distance, and direction accurately. Hemisphere -- 4 –Northern/Southern –Eastern/Western
  3. 3. Using Globes Equator Circumference = 24,902 miles Equator Diameter = 7,926 miles Polar Circumference = 24,860 miles Polar Diameter = 7, 899 miles Is the earth round? – Oblated Spheroid
  4. 4. Understanding Map Projections Map – flat drawing of all or part of earth. Cannot accurately display round earth on a flat surface Distortions -- size, shape, or distance – Equal Area – shows size – Conformal map shows shape
  5. 5. Map ProjectionsType Advantage DisadvantageMercator Shape and Distance Size at Poles Sea Navigation L&L =90Robinson Shape/Good World Map EdgeMollweide Size Shape at EdgesInterrupted Size and Shape Gaps in DistancePolar Distance/ Aerial/Navigation Around Edges
  6. 6. Interpreting Maps Title – Type of Information Legend or Key – Shows meaning of symbols Symbols – Line, color, dot, picture, or star to represent something.
  7. 7. Interpreting Maps Types – Physical – Political – Weather – Road – Population – Economic
  8. 8. Reading a Physical Map Shows features of the land and location Elevation – Height above Sea Level Sea Level – Surface of Ocean Highland – Hills, Mountains, Plateaus Lowlands – Valleys and Plains
  9. 9. Reading a Physical Map Land surface relief –Difference between highest and lowest points –High relief – sizable drops and rises in surface –Low relief – land rise or falls only slightly over a long distance.
  10. 10. Telling Directions Determine which direction first? Why? Once you know which direction is NORTH you can figure out the other directions Cardinal N, E, S, W Intermediate NE, SE, NW, SW.
  11. 11. Telling Directions Direction Arrow – indicates North Compass Rose – Shows all four cardinal and intermediate directions.
  12. 12. Using Scale Scale – line that tells how many miles or kilometers on earth that are represented by certain units on the map. Map Area – map that show a large area in a small space are limited in the details that they can show. Maps that show a small area in a large space can often show many details.
  13. 13. Using A Grid Grid – pattern of regular sections identified by a system of numbering and lettering. Horizontal and vertical lines meet to form blocks. Index – list place and grid locations in alphabetical order.
  14. 14. Latitude and LongitudeGlobal Grid – Two sets of linesParallels of latitude – HorizontalsRun all the way around the globe, never meet, parallel to the equator.Meridians of longitude – VerticalGoes halfway around the globe, meet at two points – North and South Pole.
  15. 15. Latitude and LongitudeUnit of measure – DegreesDegrees of latitude 1 = 69 milesEquator 0 latitudePoles 90 latitude
