The sloping transition between the granite of the continent and the basalt of the seabed; the true edge of a continent.

• A. Continental Margin
• B. Continental Slope
• C. Abyssal Plain
• D. Bathymetry

Answer: (B)

The sloping transition described is the edge where continental crust meets oceanic crust, a steep region that marks the true edge of the continent. This zone, the continental slope, drops from the relatively shallow continental shelf down toward the deep ocean, moving from granitic crust to basaltic crust. The broader continental margin includes the shelf and rise as well, but the specific sloping part is what defines the edge. The abyssal plain lies beyond this slope as a flat deep area, and bathymetry is simply the measurement of ocean depths, not a geographic feature.
