2What is a map?
- A map is a representation, usually on a flat
surface, of the features of an area of the earth
or a portion of the heavens, showing them in
their respective forms, sizes, and relationships
according to some convention of representation. -
-
Now what does that mean?
3- A map is a representation,
- A map is a drawing or model
- usually on a flat surface,
- of a round Earth on a flat surface,
- of the features of an area of the earth
- that shows the landforms (mountains, rivers,
etc.) - or a portion of the heavens,
- or part of the sky in a particular region,
- showing them in their respective forms, sizes,
and relationships - drawn to scale
- according to some convention of representation.
- using an accepted form of drawing or model.

4Types of Maps
- There are three basic types of maps
- PHYSICAL
- POLITICAL
- and
- THEMATIC.
-
5Physical Maps
- Physical maps show the natural features of the
Earth. - Physical maps do not contain man made features.
-
- For example, a physical map would be a map of
what you would see if you were looking down on
Earth from space.
6When you look at this map, what do you see?
Notice you do not see country borders or city
markings. These divisions are created by people.
For example, there is no actual line dividing
Texas from its bordering states. Although some
astronauts (with the use of binoculars believe it
or not) are able to see roads, large ocean
tankers, and even the Great Pyramids from space,
at very high altitudes, none of these are visible
and all you are left with are natural land
formations.
7Political Maps
Unlike physical maps, political maps show how
humans have impacted the landscape. For example,
city names, roads, country borders, etc. are all
part of political maps. Political maps change
frequently (physical maps change very, very
slowly through geologic processes) and must be
redrawn often. A political map of the world that
is 50 years old is no longer accurate. Wars
and ethnic conflict are two major causes
political maps change.

9Thematic Maps
- Thematic maps can represent a variety of
information including things like climate,
precipitation, vegetation, elevation, population,
life expectancy, etc. - Thematic maps are generally used when you are
looking at a single piece of information.

11Creating a Thematic Map
- You are now going to create a thematic map.
- You will now choose the information you will
represent on your thematic map. You may choose
to take a poll of favorite subjects, types of
music, sports, birth months, etc. Choose
something you are interested in learning about. -
- BE CREATIVE!
12The classroom is set up in the following manner
Student Desk
13Now choose what you want to know
- I would like to know which pizza toppings
students prefer to eat from the following list -
- Pepperoni, Hamburger, Cheese, or Sausage.
- I will now ask the students to choose from this
list of toppings and record the results.
14Now you must choose a way to represent the
information you have gathered. I have chosen to
use different colors so that we may see the
distribution of topping preferences.
15For example, the thematic map of my classroom may
look like this
Pepperoni
Hamburger
Cheese
Sausage
16According to this thematic map of the classroom,
which pizza topping is the most popular?

23To help us review basic geographic terms that are
used to create grids, we will play a game called
GEOrobics.
