"Geo" often refers to geography, the study of the Earth's landscapes, environments, and the relationships between people and their environments. It encompasses various aspects, including physical geography, which examines natural features like mountains and rivers, and human geography, which focuses on how human culture interacts with the environment. In addition to geography, "Geo" can also refer to geographic information systems (GIS), which are tools used to analyze and visualize spatial data. These systems help in urban planning, environmental management, and disaster response by providing insights into patterns and trends related to locations, resources, and populations.
