Geographers study the physical features of the earth and its populations. While many specialties exist, all geographers employ several methods of gathering information, including field observations, satellite imagery, and censuses. They process and interpret such information and translate it into findings relevant to the particular industry in which they’re working. Specialties include physical geographers who study the earth’s surface, the physical landscapes, and the natural environment. Human geographers focus on the relationship between human activity and their environment, which reveals insights on culture, society, and economy.
