Topographic Maps:-
Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations. A contour line is a line of equal elevation. If you walk along a contour line you will not go uphill or downhill. Topographic maps are also called contour maps.

Bathymetric Maps:
A bathymetric map is like a topographic map with the contour lines representing depth below sea level, rather than height above. Numbers are low near sea level and become higher with depth

Geological Maps:
A geologic map shows the geological features of a region Rock units are color-coded and identified in a key. Faults and folds are also shown on geologic maps. The geology is superimposed on a topographic map to give a more complete view of the geology of the region.

Summary
Earth scientists regularly use topographic, bathymetric, and geologic maps.
Topographic maps reveal the shape of a landscape. Elevations indicate height above sea level.
Bathymetric maps are like topographic maps of features found below the water. Elevations indicate depth below sea level.
Geologic maps show rock units and geologic features like faults and folds.
