The disadvantage is they are expensive and aren’t available all year round.
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
