1. "The study of movement of people, goods, and ideas from one place to another."
ex: "Movement also deals with how and why people travel from one place to another. Some people travel for career, others to be close to family, and some move to escape war or religious persecution. One example of movement was pioneers heading West on the Oregon Trail in hopes of finding cheap, fertile land in Oregon."
2. "How humans and the environment affect each other."
ex: "Geographers study the way humans interact positively and negatively with their environments. They also study the lasting affects these interactions may have on a place. Some examples of this geography theme are damming a river, polluting the air, building highways or railroads, and even watering lawns and gardens. Human behavior such as planting trees is a positive interaction with the environment where creating landfills is a negative interaction."
