1
Thinking Geographically
2
On a piece of paper Imagine and describe the most remote place on Earth you can think of 100 years ago. Now, describe how globalization has changed this place and how the people there continue to shape it –to make it the place it is today.
3
Many people have misconceptions about geography and think of the discipline as simply an exercise in memorizing place names.
4
The study of how people make places, how we organize space and society, how we interact with each other in places and across space, and how we make sense of others and ourselves in our locality, region, and world.
5
Geography exist in the global issues receiving attention at this time things such as Population growth Terrorism Cultural diffusion. Diffusion is defined as the spread of linguistic or cultural practices or innovations within a community or from one community to another.
6
Geography's importance can also be established by looking at community issues, such as: Water supply Pollution Growth management Housing Retail Openings Closures
7
In addition to political rule, boundaries can be drawn based on various components of culture including language, religion, values.
8
Where would the most desirable places to live be located? What impacts would this population increase cause?
9
Consider natural events and natural disasters. Do humans choose to live in harm’s way?
10
Geography by its nature is a spatial science. Geographers therefore study space in order to locate the distribution of people and objects. Geographers ask two main questions, “where” and “why.” Spatial analysis is concerned with analyzing regularities achieved through interaction. Regularities result in a distinctive distribution of a feature. Distribution has three properties: Density Concentration Pattern

14
4 basic directions on earth North – Never East – Eat South – Soggy West – Waffles ► Compass Rose Directional marker, a map symbol that tells you where the four cardinal directions are in relation to the map
15
Hemi = half/one side Sphere = ball/globe The equator divides the earth into 2 hemispheres Everything north of the Equator is in the Northern Hemisphere Everything south of the Equator is in the Southern Hemisphere
16
Run parallel to the Equator north and south Start at the equator 0° Latitude North of the Equator towards the North Pole up to at 90°N South of the Equator towards the South Pole up to 90°S
17
The Prime Meridian divides the earth into 2 hemispheres Everything WEST of the prime meridian is in the Western Hemisphere Everything EAST of the prime meridian is in the Eastern Hemisphere
18
Run East and West at equal intervals away from the Prime Meridian Start at the Prime Meridian 0° Longitude Are numbered up to 180° Longitude at the international dateline Are designated as either East or West of the prime meridian.
20
Fulfilling the duties of formal prayers and the pilgrimage, Muslims need to find the direction and routes leading to al Ka'ba from virtually any spot on the globe. The Ka'ba is the house of Abraham in Mecca. And it is the point at which Muslims must face when they perform prayers. Left - map of the world in 1154 by Idrissi Right - map of the world made by the Muslim geographer Jihani in the 10th century of the Christian era.

Fig. 1-2: A Polynesian “stick chart” depicts patterns of waves on the sea route between two South Pacific islands. Modern maps show the locations of these Marshall Islands.
22
Fig. 1-3: The effects of scale in maps of Florida. (Scales from 1:10 million to 1:10,000)
23
Reference Maps Show locations of places and geographic features Absolute locations What are reference maps used for?
24
THEMATIC MAPS – depict characteristics of places Categorical type - Depict areas that are different in kind - Use several distinct colors to show different categories desertforesttundra Examples: climates, religions Choropleth type - Depict areas that are different in amount - Use shades of similar colors to show different values high valuemediumlow value Examples: population density, literacy rates
25
Example of “categorical map”
26
Example of “choropleth map” Human Development Index (HDI) Rankings Includes GNI/PPP, Literacy, and Life Expectancy Which regions have high HDI? Which regions have low HDI? Which places are exceptions?

29
Fig. 1-5: A geographic information system (GIS) stores information about a location in several layers. Each layer represents a different category of information.
32
Place : Unique location of a feature Place names Site Situation Mathematical location Regions : Areas of unique characteristics Cultural landscape Types of regions Regional integration of culture Cultural ecology
33
Fig. 1-6: Site of lower Manhattan Island, New York City. There have been many changes to the area over the last 200 years.
34
Fig. 1-7: Singapore is situated at a key location for international trade.
36
Fig. 1-8: The world geographic grid consists of meridians of longitude and parallels of latitude. The prime meridian (0º) passes through Greenwich, England.
37

Fig. 1-11: The state of Iowa is an example of a formal region; the areas of influence of various television stations are examples of functional regions.
40
Fig. 1-12: A number of factors are often used to define the South as a vernacular region, each of which identifies somewhat different boundaries.
42
Fig. 1-13: Death rates from cancer in the U.S., Maryland, and Baltimore show different patterns that can identify associations with different factors.
43
Your book defines culture as a body of customary believes, material trades, and social forms that together constitute the distinct tradition of a group of people. The Latin root of culture is cultus, which means to care for. Example Agriculture (term for growing things)
44
Geographers also consider environmental factors as well as cultural factors, when looking at regions. This is cultural ecology. Basically, this is the geographic study of human-environmental relations. In the 19 th Century – some geographers said that human actions were caused by environmental conditions. (environmental determinism) This is rejected by modern geographers that say some environmental conditions limit human actions. (possibilism) Of course now we are realizing that humans can actually adjust their environment. (For good or bad)

51
What are the major Elements of culture? Customary beliefs Social customs Material traits Affects of globalization of culture Fewer local differences Enhanced communications Unequal access Difficulty in maintaining of local traditions There is also globalization of environment Sensitive and insensitive environmental modification

54
Fig. 1-20: The times required to cross the Atlantic, or orbit the Earth, illustrate how transport improvements have shrunk the world.
55
Interdependence exists among places based upon the degree of spatial interaction. Spatial interaction is established through the movement of people, ideas, and objects between regions. For example, Travel has changed considerably over the last 500 years. In the past, most forms of interaction among cultural groups required the physical movement of settlers, explores, and plunders from one place to another. Today travel by car or plane is much faster and communication is instantaneous. When places are connected to each other through a network, geographers say there is a spatial interaction between them.
56
Fig. 1-21: Delta Airlines, like many others, has configured its route network in a “hub and spoke” system.
57
Diffusion is the process by which a characteristic spreads across space from one place to another over time. The place of origin of the characteristic is called the hearth. For example – US, Canadian, and many Latin cultures can be traced back to the European Hearth. There are two basic types of diffusion: Relocation diffusion Expansion diffusion Expansion Diffusion includes- Hierarchical diffusion Contagious diffusion Stimulus diffusion
