Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Most of the oceans have a common structure created by common physical phenomena mainly from tectonic movement and sediment from various sources. Continental slope the steep slope where the contintental shelf drops to the bottom of the ocean floor.
