Geological surveys

Definition

Geological surveys are systematic investigations and assessments of the Earth's materials, structures, and processes. These surveys aim to provide crucial information about natural resources, hazards, and environmental conditions, playing a vital role in the discovery and exploitation of resources such as minerals, fossil fuels, and groundwater.
