Title: Unit 1: Introduction to Geography
1Unit 1 Introduction to Geography
- Lesson 1 The Five Themes of Geography
2What is Geography?
- Geography
- Literally means description of the earth
- It is a way of thinking about and analyzing the
earths surface, physical patterns, and human
occupation. - Geographers are people who study the earth
- Perspective
- 5 themes of geography
- Methods/tools
- Cartography
- Maps
3The five themes of geography
- Location
- Where is it?
- Place
- What is it like there?
- Movement
- How are people and places connected?
- Human Environmental Interaction
- What is the relationship between people and their
environment? - Region
- How do we classify?
4Location
- Three Types
- Nominal
- By name
- Windsor Pointe is a subdivision in Sugar Grove
- Relative location
- By Site and Situation
- Elburn is East of Maple Park
- Absolute location
- By Spatial Coordinates
- Houston, Texas, for example, is located at
latitude 29 north, longitude 95 west
5Relative Location
- Location of a place in relation to that of other
places. - Always use a direction when reporting relative
location. - Example
- The KHS football field is North of the school.
- Sugar Grove is West of Aurora
- The United States is North of Mexico
6Location
- Lets try some examples!!
- Nominal
- __________________________________
- Relative
- __________________________________
- Absolute (Use pg RA19)
- Alexandria, Egypt
- Latitude 31 North, Longitude 30 East
- Monrovia, Liberia
- Latitude 7 North, Longitude 11 West
7Site Situation
- Site
- refers to physical characteristics, such as
climate, soil type or elevation. - Site Example
- Elburn has rich topsoil
- Winters in Northern Illinois are dry and cold
- Situation
- refers to access to landmarks or transportation,
such as proximity to the White House or to Main
Street. - Situation Example
- Sugar Grove has quick access to major
transportation arteries
8Check for Understanding
Relative Location Activity
- Give the relative location of the following (use
pg RA4 5) - Indian Ocean
- Mexico
- China
- Canada
- Atlantic Ocean
9Absolute Location
- Exact position on the globe
- Grid system
- Network of imaginary lines around the earth
- Two sets of lines encircle the globe
- Latitude
- Longitude
10Latitude (Parallels)
- Parallel lines of latitude are horizontal,
running from east to west - Equator is the imaginary line from which latitude
is measured 0-90 - equidistant from the poles, dividing the globe
into the northern and southern hemispheres. - lines of latitude become progressively shorter as
they near the poles
11Longitude (Meridians)
- Longitudinal lines run from north to south
- The prime meridian is an arbitrarily selected
line from which all of the others are measured
0-180 - Each individual vertical line intersects both
poles - Lines of Longitude converge as they near the
poles - Divide the globe into Eastern Western
Hemispheres - All of the lines of longitude are the same
length.
12Just in Case you wanted to know
- Each degree of latitude and longitude is divided
into 60 minutes - Each minute is further divided into 60 seconds.
- Navigators measure distance in nautical miles
- an internationally agreed-on standard equaling
the average length of one minute of one degree,
or 1,852 m (6,076 ft).
13How do Geographers express absolute location
- Parallels of latitude north of the equator, which
lies at 0, are identified as north, and those
south of the equator are identified as south. - The North Pole lies at latitude 90 north,
- The South Pole, at latitude 90 south.
- By international agreement, the prime meridian
lies at 0 longitude. - Meridians of longitude
- East of the prime meridian are designated as east
- west of the prime meridian are identified as west.
On maps directions are abbreviated as N, S, E,
and W.
14Check for Understanding
Absolute Location Activity
15What continent is located at 1) 50 degrees N,
20 degrees E? 2) 20 degrees S, 60 degrees W? 3)
30 degrees S, 140 degrees E? 4) 0 degrees N, 20
degrees E? 5) 90 degrees S, 0 degrees E?
Equator
Prime Meridian
16Place
- What kind of place is it?
- Places have both human and physical
characteristics, as well as images. - The image people have of a place is based on
their experiences, both intellectual and
emotional. - People's descriptions of a place reveal their
values, attitudes, and perceptions. - How do these characteristics shape our lives?
17Physical Characteristics
- Physical characteristics include mountains,
rivers, soil, beaches, wildlife.
18Human Characteristics
- Places have human characteristics also. These
characteristics are derived from the ideas and
actions of people that result in changes to the
environment, such as buildings, roads, clothing,
and food habits.
19Movement
- The movement of people, the import and export of
goods, and mass communication have all played
major roles in shaping our world. - People everywhere interact.
- Interdependence
- Reliance on each other for goods, services, and
ideas near and far
20Human Environmental Interaction
- Human Environmental Interaction is how mankind
reacts to its surroundings. - Humans interact with nature every day.
- Humans react differently to everything they live
near. - There are three ways that humans interact with
nature - Humans depend on the environment for life
- Humans modify nature
- Humans adapt to nature.
21Poor Farming Techniques
Uncontrolled Air Pollution
Strip mining
Humans must be cautious of overexploitation
Deforestation
Unregulated Waste
Desertification
22Region
- Location and place are tied together by regions.
- Regions are relative locations that are brought
together by certain unifying (or common)
characteristics. - These unifying characteristics often influence
- what kinds of people inhabit these regions
- how humans interact with their environment
- how they build their cities
- how they use the land
- Unifying characteristics can be both physical and
human.
23Unifying Characteristics
- Physical unifying characteristics include such
things as mountain ranges, deserts, rivers,
climates, and landforms.
- Human unifying characteristics include language,
religious beliefs, and political attitudes.
