A Geological Survey is a scientific organization that studies the Earth's structure, composition, and processes. These surveys collect data about rocks, minerals, and natural resources, helping to understand geological hazards like earthquakes and landslides. They often produce maps and reports that inform land use and resource management. In many countries, such as the United States, the Geological Survey plays a crucial role in environmental protection and natural resource management. They collaborate with other agencies and researchers to monitor changes in the Earth's systems, contributing valuable information for public safety and sustainable development.
