  • Slide 1
  • Globes and Maps TEKS WG.13a; 21a-c,e; 22e
  • Slide 2
  • Globes Globes are three dimensional representations of the earth
  • Slide 3
  • Advantages of Globes Globes are more accurate than maps Globes are not distorted Globes are more accurate than maps Globes are not distorted
  • Slide 4
  • Disadvantages of Globes Globes are not portable Globes do not show detail Globes are more expensive than maps There are no thematic globes Globes are not portable Globes do not show detail Globes are more expensive than maps There are no thematic globes
  • Slide 5
  • Maps Maps are two dimensional representations of the earth
  • Slide 6
  • Advantages of Maps Maps are cheaper than globes Maps show detail Maps can show themes (thematic maps) and be used for comparing things Maps can be put into a book called an atlas Maps are portable Maps are cheaper than globes Maps show detail Maps can show themes (thematic maps) and be used for comparing things Maps can be put into a book called an atlas Maps are portable
  • Slide 7
  • Disadvantages of Maps Maps are distorted because the earth is not flat Maps can distort shape, area, direction, and distance This problem is somewhat solved by different map projections Maps are distorted because the earth is not flat Maps can distort shape, area, direction, and distance This problem is somewhat solved by different map projections
  • Slide 8
  • Map Projections Map projections are a way to draw maps in order to lessen distortion. There are different types of projections because people use maps for different reasons.
  • Slide 9
  • Mercator
  • Slide 10
  • The Mercator is used by ship navigators How do you identify it? a.It is square b.The latitude and longitude lines are at right angles c.The top and bottom of the map are heavily distorted (Greenland is ginormous!)

  • Slide 11
  • Great Circle Route
  • Slide 12
  • The Great Circle Route projection is used by airline pilots because it shows the shortest distance between two points How do you identify it? a.It is a circle b.It only shows one hemisphere c.The latitude lines are circles d.The longitude lines radiate from the center The Great Circle Route projection is used by airline pilots because it shows the shortest distance between two points How do you identify it? a.It is a circle b.It only shows one hemisphere c.The latitude lines are circles d.The longitude lines radiate from the center
  • Slide 13
  • Robinson
  • Slide 14
  • The Robinson projection is used to compare data. How do you identify it? a.It has curved sides b.The longitude lines curve towards the north and south pole The Robinson projection is used to compare data. How do you identify it? a.It has curved sides b.The longitude lines curve towards the north and south pole

  • Different Types of Maps Political Maps Physical Maps Topographic Maps Special-purpose Cartograms Political Maps Physical Maps Topographic Maps Special-purpose Cartograms
  • Slide 16
  • Political Maps Political maps show man-made features such as cities, states, provinces, territories, or countries (Page 18 & 19)
  • Slide 17
  • Physical Maps Physical maps help you see the type of landforms and bodies of water in a specific area (Page 20 & 21)
  • Slide 18
  • Special-Purpose Maps Special-Purpose maps show specific types of information. Here are some examples of special- purpose maps: Qualitative maps Cartograms Flow line maps Special-Purpose maps show specific types of information. Here are some examples of special- purpose maps: Qualitative maps Cartograms Flow line maps
  • Slide 19
  • Special-Purpose Maps Other types of special-purpose maps: Population distribution and density Economic activity Resource Language Ethnicity Other types of special-purpose maps: Population distribution and density Economic activity Resource Language Ethnicity
  • Slide 20
  • Special-Purpose Maps Other types of special-purpose maps: Climate Precipitation Vegetation Other types of special-purpose maps: Climate Precipitation Vegetation
  • Slide 21
  • Small Scale Maps Maps can be large or small scale A small scale map shows a large area but without much detail. A small scale is used to see relative location in a region or between regions Maps can be large or small scale A small scale map shows a large area but without much detail. A small scale is used to see relative location in a region or between regions
  • Slide 22
  • Large Scale Maps A large scale map shows a small area with much more detail A large scale is used to see relative location within a region A large scale map shows a small area with much more detail A large scale is used to see relative location within a region
