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.
