BASIC GEOGRAPHY
• Geography is the study of the relationship
between people and their physical
environment
• The name geography comes from GEO
meaning earth and GRAPHICA meaning
description.
2 Branches of Geography
• Physical Geography
– Study of earth’s physical
processes
• Geology – rocks and earth
formations
• Environmental science –
human interaction with the
environment
• Topography – earth’s
features
• Cartography – map
making.
• Human (Cultural)
Geography
– Characteristics of human
activities
• Politics – governments
• History – significant
events
• Economics – how use
resources
• Sociology – human
societies
• Urban – cities
• Demographics – human
population statistics
•7 continents – Africa, Asia, Antarctica, South America, North
America, Europe & Australia
•5 Oceans – Southern, Arctic, Pacific, Indian, Atlantic
• Globe - Scale model of the earth.
YOU ARE RESPONSIBLE FOR ALL OF THE VOCABULARY ON PAGES 14 – 15!
AKA: Parallels
Numbers get higher the further North or South
you move away from the Equator
Latitude lines measure North or
South of the Equator
Zero Degrees Latitude is the Equator
90 Degree North (North Pole)
90 Degrees South (South Pole)
MEMORIZE THESE LINES!!
KNOW: Equator, 2 Tropics, 2 Circles, 2 Poles and their latitudes!!!!
Zero Degrees longitude is the Prime Meridian. 180 degrees
East or West is the International Date Line
By international agreement - 0 degrees longitude runs through
the Royal Observatory in Greenwich, England
Numbers get higher the farther you
move either East of West
Longitude lines measure East or
West of the Prime Meridian
AKA- Meridians
Hemisheres
If you cut the Earth
through the Equator you
would get two halves, the
Northern and Southern
Hemisphere
If you cut the Earth through
the Prime Meridian you
would get two halves, the
Western and Eastern
Hemisphere
The US is in the Western Hemisphere and
the Northern Hemisphere
Each degree of the earth is equal to 1/360
of the earth. Each degree is divided into
60 minutes (‘). Each minute = 60 seconds
(“)
Globes to Maps
All maps have distortion because you are trying to take a 3-D sphere and make
it into a flat map. Distance, direction, shape, and size of land masses can be
distorted.
How do you make a sphere flat?
Cartographer- Mapmakers
(Go-cartographer)
Three basic categories are;
Planar, Cylindrical, Conic
Goode’s Interrupted EqualArea Projection Map
Planar Projection
Pro’s- 1) Accurate at center
2) Every line is a line of true direction
(Azimuthal)
and represent the shortest distance
Con’s- 1) Distorts shape
Cylindrical
Pro’s- 1) Accurate near the equator
2) Shows direction and true shape
Con’s- 1) Distorted near poles
Conic
Pro’s- 1) Limited east-west areas not too far from the Equator
2) Indicates distances and directions fairly accurately
Con’s- 1) Distorts toward poles
2) Only shows one hemisphere at a time
Common Map Projections
• Winkle-Tripel Projection- good
balance of size and shape of
land areas. The poles have
little distortion. National
Geographic Society adopted
this map type as the standard
in 1998. Computer generated
• Robinson Projection- Little
distortion, most distortion
appear at poles. More oval
than Winkle-Tripel. Computer
generated.
Goode’s Interrupted
Equal-Area
Projection- True
size and shape of
land, but distances
are distorted
Mercator ProjectionAccurate at equator,
but distorts size and
distance as you
move away from
equator. Accurately
shows true direction,
good for sea travel
and navigation.
Map Scale
Small Scale MapsShow large area with
little detail
Large Scale MapsShow small area with a lot
of detail
Reading a Map see Pg 8-9
Show a wide variety of information
Physical Maps- Show topography (shape) of earths physical features
Political Maps- Show boundaries between countries. Also may
show
cities, capitals, roads, railroads. Think man made!
Emphasize a single idea or a particular kind of
information
Economic Activity Map- Shows the distribution of land use and natural
resources.
Where lines of latitude and longitude cross they form a pattern known as a GRID
SYSTEM.
(a global address)
Absolute Location- a place found at a precise point
Ex.) Toyko, Japan is at 36 N Latitude and 140 E Longitude
Relative Location- is the location of one place in relation to another
Ex.) Sonic is across the street from Kroger
Pizza Hut is near the pyramids in Egypt
Parts of the Map
• T – Title (top of map – where, what type of
map, and when it is showing)
• O – Orientation (compass rose – n,s,w,e)
• D – Date created (bottom right corner)
• A – Author (who made it – bottom right corner)
• L – Legend (key)
• S – Scale (how big is the map compared to
real life)
• S – Source (where did you get your
information)
• I is index of all the places on the map and G is
the grid.
Places and Regions
Place- a particular space with physical and human meaning.
Region- areas united by specific factors
Formal (uniform)- common characteristic such as a product
Ex.- The Cornbelt
Functional- is an urban central point (core) and surrounding area
(periphery) that are connected to it.
Ex- New Caney is in Houston’s functional region
Perceptual- is defined by popular feelings and images
Ex.- “Heartland”
Great Circle Routes
• Shortest distance between two
points on a map!
• Maps distort distance, for
example it may look shorter to
travel between two areas on a
map than it really is.
