Title: Maps, Globes, and Atlases


1
Maps, Globes, and Atlases
2
Globe
  • World Map
  • Sphere (Ball) shaped NOT Flat
  • Actual shape of Earth
  • More Accurate than a Map

3
Maps
  • Gives us an accurate view of a neighborhood,
    city, state, country or even the world as viewed
    from above.
  • Maps are not as accurate in representation as
    globes
  • Countries appear larger (spread out)
  • Known as Map Distortion

4
Hemispheres Directions
  • If divide Earth in half each half is known as a
    hemisphere
  • Meridians lines that run north and south
  • Prime Meridian is half - 0 degrees
  • Western Hemisphere Left Half
  • Eastern Hemisphere Right Half

Prime Meridian line at 0 degrees
North
South
5
Hemispheres Directions
  • If divide Earth in half each half is known as a
    hemisphere
  • Parallels lines that run East and West
  • Northern Hemisphere Top Half
  • Southern Hemisphere Bottom Half

North
Equator at 0 degrees
West
East
South
6
Latitude Longitude
  • Latitude lines run horizontally across a globe
  • Longitude lines run vertically from the top to
    the bottom of a globe

Parallels (run East and West)
Meridians (run North and South)
7
Latitude and Longitude
  • Have measurements called degrees
  • Prime Meridian imaginary line that passes
    through Greenwich, England is 0 degrees runs
    north to south
  • Equator 0 degrees runs east to west
  • 180 degrees International Date Line imaginary
    line that marks the spot where each new calendar
    day begins

8
Scale (In Mapmaking)
  • Size Map is exactly proportional to size of area
    being pictured
  • Scale aids in measuring distance
  • Measurement equals a certain amount of distance.
    (1 inch 200 miles)
  • Scale is located somewhere on the map
  • Not all scales are the same

9
Grids
  • Lines used to help locate places on a map
  • Go Across then Down

Insets
  • Portion of a map made larger to show detail.

11
Map Symbols Map Keys (Legends)
  • To identify features on the maps
  • Symbols designs or colors on a map (mountains,
    parks, airports, etc)
  • Key (Legend) explains what the symbols represent

airport
Park
12
Types of Maps
  • Political Maps
  • Shows lines that divide up an area
  • Shows boundaries created by people and nature
  • Can change as land is divided up or countries
    change
  • Show capitols of states and countries
  • Insets boxed off area in corner larger scale
    to show more detail or to reduce distance (Hawaii
    or Alaska)

13
Types of Maps
  • Physical Maps
  • Picture the physical feature of land, a state or
    country
  • Formations such as mountains, hills, volcanoes.
  • Bodies of water and their depth
  • Political Maps and Physical Maps often shown on
    same map

14
Relief Maps Globes
  • Maps - Mountains appearing as though they are
    rising off the paper on maps
  • Use art technique of shading to create
  • Globes - Mountains stand out so that you can feel
    the ridges as you run your fingers along the
    mountains.

15
Contour Maps
  • Accurate method of picturing elevation
  • Viewing area from above to get measurement of
    elevation
  • Heights are converted to contour lines
    representing these heights
  • Lines are different colors to represent the height

16
Distribution Maps
  • Use to give information other than locations
  • Types of food grown
  • Population
  • Natural resources (trees, oil, minerals)
  • Wealth
  • Understand area at a quick glance

17
Political Maps
  • represent the political units of the world
  • a political map of a state shows county names and
    boundaries
  • political map of the world features country names
    and boundaries

18
Road Maps
  • Travel maps
  • Large scale maps used to figure out how to get
    somewhere
  • Very detailed with road names, exit numbers, type
    of road
  • Indicates mileage

19
Historical Maps
  • Historically correct for the time period they
    represent.
  • Usually found in social studies books or history
    books
  • Teach us about how countries were settled
