Geologic Map of the United States

A geologic map of the United States shows the distribution, types, and ages of rocks beneath the surface across the country. It uses different colors and symbols to represent various geological formations, faults, and features, helping scientists understand the Earth's history and processes. This information is crucial for natural resource exploration, environmental management, and assessing hazards like earthquakes or landslides. The map provides a detailed view of how the Earth's crust varies across regions, reflecting millions of years of geological activity that shapes the landscape we see today.
