Geography is the study of the Earth's physical features, climate, vegetation, and human populations. It is a field, focusing on how natural and human-made factors shape the world we live in. The field of geography encompasses several sub-disciplines, including physical geography, human geography, and geographic information systems (GIS). GIS involves the use of technology to gather, analyze, and present geographic data. Geographers employ various research methods to study the Earth and its phenomena. They use remote sensing techniques, satellite imagery, and geographic information systems to collect and analyze spatial data. Fieldwork, surveys, interviews, and statistical analysis are also common methods used to gather information and draw conclusions.
