Basic Geography Skills
  • WG SOL 1

2
Two types of maps
  • General Purpose includes political and physical
    maps
  • Thematic A thematic map displays special
    features such as population, climate, vegetation,
    precipitation etc.

3
Political and Physical Maps
  • Physical Maps
  • Political Maps
  • Physical maps represent what a region looks like
    by showing its major physical features, such as
    hills and plains.
  • Political maps show political borders continents
    and countries.
  • Political maps also include symbols and labels
    for capitals, cities and towns.

4
Important Map Terms
  • Compass Rose shows map orientation
  • (north, south, east, and west)
  • Scale shows what a measurement on a map is
    equal to in real life
  • Legend a key

5
Location, location location 2 Types
  • Absolute location specific address, latitude or
    longitude
  • Relative location in relation to another place
    north/south/right/left etc.

6
Sources of Geographic Information
  • GIS-Geographic Information Systems
  • Satelite Images
  • Maps
  • Databases
  • Field work
  • Photographs
  • Globes

7
Maps show information using
  • Symbols ? a church
  • Colors represent changes in elevation, water is
    usually blue
  • Lines usually a river
  • Boundaries usually a bold line
  • Contours lines indicate changes in elevation

8
  • Mental Maps
  • Mental Map is a map produced by someones mind
  • Uses 1. daily activities such as going to
    school or driving to church
  • 2. Give directions
  • 3. Understand world events
  • Ways developed and refined
  • 1. Comparing to a real map
  • 2. Describing the location
  • 3. Describing the relative location

9
Understanding Globes
  • Lines of Latitude Imaginary horizontal lines
    around the globe.
  • Also called Parallels

Lines of Longitude Imaginary vertical lines
around the globe. Also called Meridians
Together, these lines form the global grid. Every
place on the earth has its own set of coordinates
on the global grid.
10
How Latitude and Longitude Form the Global Grid
11
The Hemispheres
12
  • Which 2 hemispheres do we live in?

13
THE GLOBAL GRID
The Earth is divided by latitude and longitude
lines. There are several important lines to know
on the earth's surface
1 is the ARCTIC CIRCLE found at 66 ½ o NORTH of
the Equator 2 is the TROPIC OF CANCER found at
23 ½ o NORTH of the Equator
3 is the EQUATOR which splits the earth into two
hemispheres at 0o Latitude 4 is the TROPIC OF
CAPRICORN found 23 ½ o SOUTH of the Equator. 5
is the ANTARCTIC CIRCLE found at 66 ½ o SOUTH of
the Equator
6
6 is the PRIME MERIDIAN which runs north to
south at 0o LONGITUDE
14
Pencils down.....just listen! Use the pink map
cards....
15
East West, North South on the Earth
  • The N tells us were north of the Equator. The S
    tells us were south of the Equator.
  • The E tells us that were east of the Prime
    Meridian. The W tells us that were west of the
    Prime Meridian.

(N, W)
(N, E)
(S, W)
(S, E)
16
East West, North South on the Earth
  • That means all points in North America will
    have a North latitude and a West longitude
    because it is North of the Equator and West of
    the Prime Meridian.

(N, W)
Prime Meridian
17
East West, North South on the Earth
  • What would be the latitude and longitude
    directions in Australia?

?
Prime Meridian
If you said South and East , youre right!
18
So Where is (0,0)?
  • The origin point (0,0) is where the equator
    intersects the prime meridian.
  • (0,0) is off the western coast of Africa in the
    Atlantic Ocean.

19
See If You Can Tell In Which Quarter These
Lon/Lats Are Located
  • 1. 41N, 21E
  • 2. 37N, 76W
  • 3. 72S, 141W
  • 4. 7S, 23W
  • 5. 15N, 29E
  • 6. 34S, 151E

In Summary!
21
Positioning on the Earths Surface
Latitude and Longitude together enable the
fixing of position on the Earths surface.
22
Now youre ready to find some locations on a map!
23
Activity
  • Bingo with Latitude

24
Honors Assignment Create a Map
  • You will be using a mental map to create a paper
    map.
  • The mental map will be your route to school.
  • Be sure to include your TODALS!
  • You will also include step by step written
