Geography is the study of places on Earth and their relationships with each other. Often the study of geography begins with one's home community and expands as a person gains greater experience. Thus geography provides a conceptual link for children between home, school and the world beyond. Geographers study how people interact with the environment and with each other from place to place and they classify the earth into regions in order to draw generalizations about the complex world in which we live. Because it deals with where and how people live, geography is rich in material that relates to international understanding, multi cultural concerns and environmental educations.
