Geographers study the material and symbolic transformation of the earth in relationship to both human and natural processes. In keeping with contemporary global shifts in culture, the environment, politics and economics, the boundaries of the geographic discipline are dynamic. For example, environmental change, international development, globalization, and new spatial technologies exemplify important arenas of study in geography. Theories of space, scale, location, place, region, mobility and displacement allow geographers to critically analyze change in both human and physical environments.
Geography is both a natural science and a social science as it examines people and their environment and serves as a bridge between the physical and cultural worlds.
