This chapter introduces the key concepts of geography. It defines geography as the study of the Earth, including both physical and human elements. Physical geography is divided into four components: the biosphere, hydrosphere, atmosphere, and lithosphere. Human geography also has four components: population, settlements, development, and culture. The chapter also outlines four core geographical concepts: place, space, scale, and environment. Students are assigned tasks to further their understanding of these foundational geographical terms and concepts.
