| @Zak6009: According to Merriam-Webster, the definition of "geography" is (1) a science that deals with the description, distribution, and interaction of the diverse physical, biological, and cultural features of the earth's surface, and (2) the geographic features of an area. Question 18 definitely falls within the category of "geography." Specifically, it's "physical geography." Wikipedia describes physical geography as "one of the two major subfields of geography. Physical geography is that branch of natural science which deals with the study of processes and patterns in the natural environment like the atmosphere, hydrosphere, biosphere, and geosphere, as opposed to the cultural or built environment, the domain of human geography." |
