B. Both continental and ocean-floor topography are measured relative to sea level
Explanation:
On a topographic map, both continental and ocean-floor topography are measured relative to sea level.
The sea level is the reference surface for the continental and ocean floor topography.
- A topographic map is a map that shows landform using series of contour lines.
- The lines joins places of equal elevation.
- The elevation is usually referenced to the sea level surface.
- The sea level is taken as the surface with 0 depth or height.
- Continental topography is all places above the sea level.
- Ocean floor is below the sea level surface

The answer is friction. As ocean wave approach the shoreline, they are affected by the sea bed through process such as refraction, shoaling, bottom friction and wave-breaking. However wave breaking also occurs in deep water when the waves re too steep. If the waves meet major structurer or abrupt changes in the coastline, they will be transformed by diffraction.
