This document introduces physical geography and some of its key concepts. It begins with an overview of what geography is, including its Greek roots and some of the earliest geographers. It then discusses the five fundamental concepts of geography - location, place, movement, human-environment interactions, and regions. The document outlines the main subfields of physical geography, human geography, and geomatics. It introduces concepts of systems science, including open and closed systems, feedback, equilibrium, and Earth's four spheres of atmosphere, lithosphere, hydrosphere, and biosphere.
![Systems Science
► What is a “system”?
A system is “a set of things, structures,
processes, [or] activities…[that are] associated
and interconnected, forming and functioning as
a complex whole through a regular set of
relations….”
--Audrey N. Clark’s Dictionary of Geography

GEOG100--Lecture 01--What is Geography?
- 1. Welcome to Physical Geography With Angela (Skinner) Orr Lecture #1 1
- 2. What is Geography? You might have thought, before taking this course, that Geography is all about:
- 3. What is Geography? You might have thought, before taking this course, that Geography is all about: ► Maps
- 4. What is Geography? ► Where things are in the world
- 5. What is Geography? ► The study of Earth
- 6. What is Geography? ► Earth’s landforms
- 7. What is Geography? ► How humans and the environment interact with one another
- 8. What is Geography? ► (What else?)
- 9. What is Geography? If you thought geography was about any of these, you are correct. Geography is about all of these things… …AND MORE!!!
- 10. The most important question in Geography is: Why is it there?
- 11. Where did “Geography” come from? Geo- comes from Greek “ge” = “Earth” geoid geology geometry -graphy comes from Greek “graphe” = “writing” or “description” (Does it remind you of “graph”?)
- 12. Who were the first geographers? The Greeks were not the first to “do” Geography… Mesopotamian land ownership map on a clay tablet
- 13. Who were the first geographers? Egyptian gold mine map on papyrus
- 14. Who were the first geographers? ► The Greeks codified it, broadened it, deepened it, named it, lived it ► These were the first geographers in the Western tradition, and their ideas have been handed down over thousands of years ► The real reason we follow in the Greeks’ footsteps? The ideas contained in their works survived and were translated into other languages
- 15. A Brief History of the Early Development of Geography ► Western Geography—Greece and Rome Development of geometric principles Eratosthenes, Hipparchus, Strabo and Ptolemy
- 16. Asian Geography ► Academic knowledge was highly-prized ► Japan, Korea, and China all were engaging in extensive trade long before European explorers
- 17. China ► Expansion of the Chinese empire Needed to know what was IN that empire (resources, cultures, wealth, areas of potential political threats or alliances, etc.) ► Chinese geographers created extensive maps, wrote detailed descriptions of culture groups and physical environments
- 18. Muslim Geographers ► One of the tenants (the 8 “pillars”) of Islam is that every able-bodied Muslim must make a pilgrimage to the holy city of Mecca (in what is, today, Saudi Arabia) at least once in a lifetime ► Pilgrimages to Mecca offered opportunities for observation and description, from Africa to Spain to India and throughout Southwest Asia ► As these pilgrims traveled, they wrote about what they saw and experienced, and mapped out land and seas
- 19. Immanuel Kant—18th Century philosopher ► Order out of chaos He proposed three Categories of Academic Disciplines…
- 20. Immanuel Kant—18th Century philosopher ►Categories of Academic Disciplines: 1. Systematic Sciences—orderly, methodical, subject matter is easily classified (Physics, Geology, Botany, Zoology, etc.) 2. Temporal Sciences—the dimension of time (History, Archaeology, Paleontology) 3. Spatial Sciences—the dimension of space (Geography, Geophysics*, Astronomy) The map is a geographer’s primary spatial tool
- 21. The Fundamentals ► Every study of Geography incorporates one or more of the following 5 Fundamental Concepts in Geography: 1. Location 2. Place 3. Movement 4. Human-Environment Interactions 5. Region
- 22. The 5 Fundamental Spatial Concepts of Geography ► 1. Location—study of where something is found in Earth space
- 23. The 5 Fundamental Spatial Concepts of Geography ► 2. Place—study of the site and situation characteristics of a particular portion of space
- 24. The 5 Fundamental Spatial Concepts of Geography ► 2. Place—study of the site and situation characteristics of a particular portion of space “Sense of Place” is an important geographical concept
- 29. sense of place an artist’s interpretation
- 30. JIMMY BUFFETT “MARGARITAVILLE” GLADIATOR ? THE PERFECT VACATION Sense of Place some “imaginary” places
- 31. The 5 Fundamental Spatial Concepts of Geography ► 3. Movement—study of the circulation of objects, people, and ideas, and their distribution (spatial patterning) on Earth’s surface
- 32. The 5 Fundamental Spatial Concepts of Geography ► 4. Human-Earth Interactions—study of how humans perceive, use, and alter the planet, and how the environment affects and changes humans, in return 32
- 33. The 5 Fundamental Spatial Concepts of Geography ►5. Region— study of an area on Earth’s surface that exhibits some form of spatial cohesion reflected by a homogeneity of specific features or functional linkages to a central node (WHAAAA???)
- 34. Functional linkages to a central node Homogeneity of specific features
- 35. Geography is holistic ► Interested in interrelationships ► Informed by many other sciences Geography is actually the Mother of many other fields of science ► Test your professor: Name a field which cannot in some way be studied by a geographer
- 36. AAG Specializations ► AAG: Association of American Geographers' M http://www.aag.org/cs/membership/specialty_g roups
- 37. The Subdivisions of Geography ► Geography can be divided into any number of subfields. The main divisions are: Physical Geography ►Biogeography is sometimes considered a part of physical geography Human Geography Geomatics (Technical Geography)
- 38. Physical Geography ► Physical geography is the study of Earth’s natural systems, their spatial distributions, and interactions. It is the study of the natural and human-induced processes that shape the surface of our planet. Subfields include geomorphology, climatology, hydrogeography, etc. Maintains connections with other physical sciences
- 39. Biogeography ► The study of the spatial distribution of plants and animals. Subfields include phytogeography, zoogeography, pedology (cross-over with physical geography), etc. Often considered a subfield of Physical Geography
- 40. Human Geography ► The study of how people use the land, how they perceive it and relate to it; the spatial variations between human groups Subfields include: cultural geography, economic geography, urban geography, political geography, ethnic geography, geodemography, religious geography, geolinguistics, proxemics, etc. Maintains connections with all other social sciences
- 41. Geomatics/Technical Geography ► All of the technical specialties within the field which assist geographic studies. Cartography (GIS) Remote sensing Statistical studies Maintains connections with information technologies, mathematics, computer sciences, etc.
- 42. Systems Science ► What is a “system”? A system is “a set of things, structures, processes, [or] activities…[that are] associated and interconnected, forming and functioning as a complex whole through a regular set of relations….” --Audrey N. Clark’s Dictionary of Geography 43
- 43. Systems Science 44
- 44. Systems Science ► Flow system—matter and/or energy moving around Open system—has inputs and outputs Closed system (also called a cycle)—constantly transforming and reusing what’s already there; nothing ever leaves 45
- 45. Systems Science ► Feedback Positive feedback ►When the result of a process causes conditions which strengthen that process and increasingly amplify its results Feedback from an amplifier Arctic ice melting Negative feedback ►When the result of a process causes conditions which weaken the process and reduce its effects An air conditioning system More water in Earth’s atmosphere creating more clouds that reflect and scatter sunlight 46
- 46. Systems Science ► Time cycles--systems operate on all different scales, including time scales, large and small 47
- 47. Systems Science ► Earth’s systems are always attempting to achieve equilibrium, in which exchanges of matter and/or energy are equal, in and out ► Equilibrium is difficult to attain and even more difficult to maintain over long time cycles 48
- 48. Systems Science ► Sometimes a series of slight changes might result in a larger change that pushes the system over a threshold, a point at which the same state can no longer be maintained 49
