geological map

Earth structure diagram

A geological map shows the distribution of rock types, formations, and structures across an area of land.

Unlike topographic maps that show surface features, geological maps reveal what lies beneath—different rock units distinguished by color, with symbols indicating faults, folds, and the orientation of rock layers.

The geological map showed limestone underlying most of the valley.
