How do topographic maps compare in their representation of continental and ocean-floor topography?

Topographic maps represent continental and ocean-floor topography differently due to their distinct features. Continental topography includes elevations like mountains, valleys, and plains, often depicted with contour lines and shading to indicate height. In contrast, ocean-floor topography focuses on features such as mid-ocean ridges, trenches, and seamounts, typically using bathymetric contours to illustrate depth changes. While both types of maps convey elevation and depth, their scales and symbols are tailored to the unique characteristics of land and underwater landscapes.
