Themes of Geography:Location: where it's at
... Absolute location = lat. and long.; Relative location, in terms of time, distance, and / or, direction from a known location.Place: what it's like there
... based in "signature traits" of place: Physical traits = what nature put there (flora, fauna, topography,climatic elements, etc.); Cultural traits = man made, caused, or induced things present... crops, roads, cities, diversions of watercourses, etc.Interaction: what we do there
... in terms of natural traits of place, how we interact with nature to "make a living" [used to be called human-environmental interactio] Movement: interaction between or among places
... in terms of cultural traits; how "our place" (we) interacts with "other places" (them) nearby. The movement of people, ideas, goods, services, money, anything that can flow from one place to another demonstrates this concept.Region: an area that you can define
... as being similar within the bounds you set or different fro that which is outside of the bounds you set. A "place can be in multiple overlapping regions. [sometimes a hard concept to grasp since the you determine the parameters of your region based on what you are studying.
Hope this helps.
