A geographer is a professional who studies the Earth's landscapes, environments, and the relationships between people and their environments. They analyze physical features like mountains, rivers, and climate, as well as human-made elements such as cities and transportation systems. Geographers often use tools like maps, Geographic Information Systems (GIS), and satellite imagery to gather and interpret data. In their work, geographers may focus on various subfields, including physical geography, which examines natural processes, and human geography, which explores cultural and economic activities. Their findings can help inform urban planning, environmental conservation, and disaster management strategies.
