Title: Unit 1 Physical Geography


1
Unit 1Physical Geography
  • Chapter 1

2
What is Physical Geography?
  • Write 2 sentences about what YOU think physical
    geography is
  • You have 3 minutes

3
Geography
  • The study of the physical and human landscapes of
    Earth and the interaction between the two
  • Physical Geography the study of Earths
    physical features
  • Human (Cultural) Geography the study of human
    activities and their relationship to the cultural
    and physical environments
  • Geographers specialize on the interaction between
    humans and the Earth

4
Physical Environment
  • Consists of physical features that occur
    naturally
  • 4 Major Components
  • Water
  • Natural Vegetation
  • Landforms and rocks
  • Weather and Climate

5
Rocky Mts.
Rio Grande
Carlsbad Caverns
Red Sands
White Sands
Elephant Butte
6
Exploring Geography
  • The world is usually described in spatial terms
  • Spatial relations- refer to the links that places
    and people have to one another because of their
    location
  • You could use the terms-
  • Absolute location
  • Relative location

7
I. Absolute Location
  • Absolute location - The exact spot at which the
    place is found on the globe
  • To determine absolute location, geographers use
    imaginary lines around the earth
  • What lines are they?

8
Imaginary Lines
  • Equator divides the earth into Northern and
    Southern hemispheres
  • Prime Meridian divides the earth into Eastern
    and Western hemispheres (Greenwich, England)
  • Latitude degrees north or south of the equator
    (0-90)
  • Longitude degrees east or west of the Prime
    Meridian (0-180)

9
Compass RoseActivity
  • Do you know how to tell direction?
  • In your notebook write down the saying you know
    in order to find out direction
  • Do not share your answer with anyone

10
Equator Prime MeridianIn which
hemisphere do you live?
11
Grid System
  • Grid System - Used to identify absolute location
    of any place on Earth
  • Measured in degrees and direction
  • What lines are measured with degrees?
  • How is direction measured?

12
Grid System
13
World Map Activity
  • Each person needs a blank world map
  • Locate the following
  • North Pole
  • South Pole
  • Equator
  • Eastern Hemisphere
  • Western Hemisphere
  • Prime Meridian
  • Northern Hemisphere
  • Southern Hemisphere
  • Tropic of Cancer
  • Tropic of Capricorn
  • Draw your Compass Rose and identify degrees

14
Grid System Activity
  • You will have a partner
  • Latitude is measured 0-90 North or South
  • Longitude is measured 0-180 West or East
  • When plotting it goes latitude then longitude Ex
    (5N, 125)
  • Locate the following absolute locations
  • (15S, 60W)
  • (28S, 125E)
  • (35N, 130E)

15
II. Relative Location
  • Relative location - location of a place in
    relation to other places
  • This is usually how we determine location
  • Socorro High School is next to Churches Chicken
    or Vista
  • Identify 5 different places using relative
    location

16
III. Places
  • Place a particular space with physical and
    human meaning
  • Every place has its own unique characteristics,
    determined by the surrounding environment and the
    people who live there
  • What is the most important place to you in the
    world and why?

17
IV. Regions
  • Region a group of places united by similar
    characteristics
  • May be physical such as soil type, vegetation and
    climate
  • Or by human factors such as language, religion,
    forms of government, etc
  • Name 5 regions that you already know

18
Three types of Regions
  • Formal (uniform) defined by a common
    characteristics such as a product produced there
    or climate experienced there
  • The Corn Belt Iowa-Illinois area in the US
  • Common Characteristic?
  • Islamic World Middle East
  • Common Characteristic?

19
Functional Region
  • Functional - a central place and the surrounding
    area linked to it
  • Group of places that help each other function
  • Metropolitan areas such as LA or Tokyo
  • What common characteristics do these areas have?

20
Perceptual Region
  • Perceptual - defined by popular feelings and
    images rather than by objective data
  • Heartland
  • Its what YOU think an area is
  • Hollywood!

21
Perceptual Region Activity
WEST SIDE LOWER VALLEY
EAST SIDE NORTHEAST
Write 10 characteristics about each area
22
V. Physical Systems
  • Physical Systems-The physical processes that
    shape the patterns on Earths surface

El Paso Floods
Volcanoes
Hurricane Katrina
23
Ecosystems
  • Ecosystems- Community of plants and animals that
    depend upon one another, and their surroundings
    for survival
  • Geography look at how physical features interact
    with the ecosystems

24
ECOSYSTEMS! Name 5 different processes within
Ecosystems
25
VI. Human Systems
  • Geographers study how people shape the Earth
  • Theme in Geography MOVEMENT
  • Movement ongoing movement of people, goods and
    ideas
  • People compete or cooperate with each other to
    either change or control aspects of the Earth to
    meet their needs
  • Write 2 sentences as to why you think movement is
    important..

26
VII. Human-Environment Interaction
  • Another theme of Geography
  • HEI- The study of the interrelationship between
    people and their physical environment
  • Environment
  • Mountains and deserts often pose barriers to
    human movement
  • Humans
  • Building a dam, alters the physical environment

27
Examples of Human-Environment Interaction
  • How do people use their environment?
  • How and why have they changed it?
  • What consequences result from those changes?

28
Use of Geography
  • Geography gives us insight into how physical
    features and living things develop in the past
  • It is important to apply all these concepts with
    events that are going on in the world TODAY!!

29
Geographers Craft
  • Geographers use tools to help them analyze
    information
  • Population Pyramids
  • Population Density Maps
  • GPS (Global Positioning System)
  • GIS (Geographic Information Systems)
  • Cartography
  • Direct Observation
  • Interviewing
  • Statistics
  • Technology

30
Writing Journal
  • Imagine you are an urban planner.
  • What kinds of data might you want to assemble in
    order to plan a location for a new school?
  • What methods will you use to collect your data?
  • How would you use the data to determine the
    location for the school?
  • Explain your choices in a paragraphs
