Globes
▪ Globes are three dimensional representations of the earth

Advantages of Globes
▪ Globes are more accurate than maps
▪ Globes are not distorted

Disadvantages of Globes
▪ Globes are not portable▪ Globes do not show detail▪ Globes are more expensive than
maps▪ There are no thematic globes

Maps
▪ Maps are two dimensional representations of the earth

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

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

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.

Mercator▪ The Mercator is used by ship navigators
How do you identify it?a. It is squareb. The latitude and longitude lines are at
right anglesc. The top and bottom of the map are heavily
distorted (Greenland is ginormous!)

Polar
▪ The Polar projection is used by airline pilots because it shows the shortest distance between two points
How do you identify it?a. It is a circleb. It only shows one hemispherec. The latitude lines are circlesd. The longitude lines radiate from the center

Robinson▪ The Robinson projection is used to
compare data.How do you identify it?
a. It has curved sidesb. The longitude lines curve towards the
north and south pole

Different Types of Maps
▪ Political Maps▪ Physical Maps▪ Topographic Maps▪ Thematic Maps▪ Cartograms

Political Maps
▪ Political maps show man-made features such as cities, states, provinces, territories, or countries (Page 21)

Thematic Maps▪ Thematic maps show specific types
of information. Here are some examples of thematic maps:
