1 Introduction to AP Human Geography

2 Introductory Questions 1) Why do students study geography? (3 examples) 2) How does geography affect your life? (3 examples) 3) How would your life be different if you lived in Japan? (3 examples)

3 Intro. Cont.. I. In this course, we will examine why different areas have developed differently in terms of culture, economics, politics, and urban development. II. Geography is a means to understand why certain areas are similar to and different from each other. Human geography in particular, helps us to focus on how the world is and how it might be. III. Geography is a means to understand why certain areas are similar to and different from each other. Human geography in particular, helps us to focus on how the world is and how it might be.

4 Intro. Cont I. Human geography is different from other branches of geography because its primary focus is people. It studies human groups and their activities, such as language, industry, and the building of cities; it is a social science. (It looks at how people modify their environment, how they interact over space, as opposed to with space). II. Other Fields of Geography i. Population geography The study of the distribution of humankind across the earth ii. Cultural geography The study of the geography of human cultures iii. Political geography The study of the interaction between political processes and the distribution of all other activities iv. Economic geography The study of how various people make their living and what they trade v. Urban geography The geographic study of cities vi. vii. Physical Geography The study of the characteristics of the physical environment Historical Geography The study of the geography of the past and how geographic distributions have changed.

5 Are You a Geo-Genius 1) Which state is bordered on the southwest by the Savannah River- South Carolina or Indiana? 2) Which state produces more gold than any other state- Nevada or Nebraska? 3) Which state is located closer to the Tropic of Cancer Louisiana or Wyoming? 4) Which state has a longer border with Canada Alaska or Idaho? 5) Which state does not have a coastline New Mexico or New Hampshire?

6 Chapter 1 Introduction to Geography

7 History of Geography Classical Western World (1) Erastosthones ( B.C.) Director of library in Alexandria, calculated circumference of the Earth Hipparchus ( B.C.) Alexandria library director, first two place a grid on the earth (2) Ptolemy ( 127 A.D. 150) Wrote Guide to Geography Non-European World Muslim Scholars - Al-Edrisi ( ), Ibn-Battuta ( ), and Ibn-Khaldun ( ) produced texts The Tribute of Yu 5 th Century B.C. describes geogrpahy of Chinese Empire Phei Hsiu father of Chinese cartography (3) Kangido Korea 1402, included East Asia, India, Islamic World, Africa, and Europe, far more extensive than knowledge of the Roman World

8 Since the 1400 s General geography (1650) Bernhard Varen German professor (4) Special geography = regional geography, begins with explanation of local physical env. and then analyzes places in terms of categories, such as local population, customs, and politics. (5) General geography = topical/systematic geography, examines topics of universal application, basic approach for the outline of your textbook Human-environment tradition (6) Alexander von Humboldt ( ) Cosmos enormous intellectual impact in the United States, statue central park (7) George Perkins Marsh ( ) Man and Nature (1864) U.S. ambassador to several Mediterranean countries, precursor of today s env. movement

9 The information that any citizen needs in order to make an informed decision on an important question of the day is largely geographic.

10 Geography Today Association of American Geographers (8) 55 topical specialties Where?, What?, When?, Why?, and Why there? Four approaches Area analysis examines site, situation, and region. Spatial analysis examines patterns in the distribution of human actions, movements and env. processes across Earth s surface (9) Physical System Analysis use models to analyze physical env. Geographic information systems analysis use computer based GIS and GPS systems

11 Area Analysis Site (10) Exact location of a place Situation or relative location Location of a place relative to other places Accessibility (11) Constant change Scale

12 Regions Formal regions Exhibit uniformity across a cultural or physical characteristic Functional regions Defined by interactions among places Vernacular regions (12) Widespread popular perception of existence

16 Spatial Analysis Distribution the distribution of a phenomenon means its position, placement or arrangement throughout space Three properties of distribution (13) Density describes the frequency of occurrence of a phenomenon in relation to a geographic area (fig. 1-11) Concentration refers to the distribution of a phenomenon within a given area (14) Pattern geometrical arrangement of objects in an area

17

18 Movement Distance Interaction of people and places across distance Measurements (several ways to measure) (15) Absolute measured in terms of miles or kilometers Time i.e. something is 20 minutes away Cost monetary amount required to overcome a distance (explains importance of water to growth of cities) (16) Friction of distance effort to overcome distance when we transport items Distance decay As distance increases, importance of a particular phenomena decreases Ex. Newspaper circulation

19

20 Three Types of Diffusion (17) Relocation diffusion i.e. a nomadic tribe relocating Contiguous diffusion occurs from one place directly to another place (18) Hierarchical diffusion upward or downward in an organization (Roman Catholic Church) Barriers to diffusion Cultural barriers Oceans, deserts, distance, time Political boundaries, cultural differences

21

22 4 Physical Systems Atmosphere (air) surrounding Earth to an altitude of less than 300 miles (lower atm. pure air is 78% N and 21% O) (19) Lithosphere (Earth s solid rocks) consists of Earth s crust and a portion of upper mantle directly below the crust, extending down 45 miles Hydrosphere (water) surface water, vapor in the atmosphere, ice in glaciers, and groundwater in soil and rock (20) Biosphere - living organisms on Earth

23 Human-Environmental Interaction (21) Reciprocal interaction env. affects human life and cultures and humans alter the env. Culture Everything about the way people live: language, food, religion, social ceremonies (22) Natural landscapes Without evidence of human activity Cultural landscapes Reveals how humans modify local environment

24 The Geographic Grid Longitude Measures distance east to west around the globe beginning at the Prime Meridian Prime Meridian 0 Degree International Date Line see figure degrees East or West (23) Greenwich Mean Time Latitude Location on the Earth s surface between the equator and either the north or south pole (24) Parallels lines connecting all points at the same latitude 0-90 degrees North or South

27 Map Making Cartography Scale Fraction 1/24,000 Ratio 1:24,000 Written statement 1 inch equals 1 mile Bar style Detail and area (25) Small scale map = less detail, large denominator (1:1,000,000) (26) Large scale map = more detail, small denominator (1:100,000)

30 Projection Scientific method of transferring locations on Earth s surface to a flat map 4 types of distortion (see page 30) (27) Shape objects are stretched more in some parts so that their shape changes Distance latitude and longitude lines (28) Relative size items become larger or smaller Direction lat. & long. orientation changes

31

32 Geographic Information Technology Automated cartography Manual techniques - expensive (29) Computer Assisted Drawing (CAD) Sophisticated, specialized digital cartography systems Easier, cheaper editing Also used for product design, i.e. Cannondale

33 Natural Landscape w/o evidence of human activity

34 Cultural Landscape - Reveals how humans modify local environment

35 Questions: 1) When does an area become a cultural landscape and stop becoming a natural landscape? 2) Are all landscapes cultural landscapes? 3) How much of land in the U.S. should be preserved?

36 Accessibility can be as valuable as mineral deposits or fertile soil Accessibility Survey 1. How accessible is NYC? Philadelphia? Tanzania? 2. How accessible are your teachers? 3. How accessible are you, can your friends easily contact you? 4. How might your answers have been different 50 years ago? 5. What are the positives and negatives of increased accessibility?

37 Remote Sensing Acquisition of data about Earth s surface from a satellite orbiting the planet or from high-flying aircraft

38 Satellites (30) Landsat see page 35 First launch 1972; most recent launch 1999 Sensors measure radiation of colors of visible light Pixel size at first (resolution): 59 x 59 meters IKONOS resolution now: 1.5 x 1.5 meters Weather satellites Very large pixels cover several kilometers on a side

39

40 Remotely Sensed Data Human activities Changes in plant growth Drainage patterns Erosion associated with agriculture (31) Logging and forest management Wetland monitoring Wartime applications

41

42 GIS (32) Geographic Information Systems Database software for digital information Contains same information as regular database PLUS Spatial characteristics such as boundary information or coordinates An identifying characteristic that locates the item in space (i.e., address) Layers Information with specific characteristics Soils, hydrology, land ownership Can be combined for analysis

43

44 Digital Geographic Information (33) Raster Grid cells of data Remote sensing images Pixels (34) Vector Point, line, polygon data X and Y coordinates Different uses and spatial accuracies

45 Digital Data Conversion of paper to digital formats Digital database creation Remote sensing images Digitizing Tracing lines Available types of data (35) Topographic maps DRG and DLG US Fish and Wildlife Service National Wetlands Inventory Census Bureau TIGER files

46 GIS Spatial Analysis Calculating densities and distribution of population Counting lakes Monitoring environmental changes with satellite images Analyzing changes in (36) food production and land use
