Continental Drift
The seaward edge of the continental shelf is marked by the shelf break, which is the steep slope that descends from the continental shelf to the deep ocean floor. This is where the ocean depth abruptly increases, indicating the boundary between the continental shelf and the continental slope.
Floating Icebergs
Floating Icebergs
Chunks of continental glaciers that break off from the edges of the ice sheets produce icebergs. These icebergs can drift in the ocean and pose a hazard to navigation.

Continental Drift
During the Ice Age.
The three parts of the continental margin are the continental shelf, continental slope, and continental rise. The continental shelf is the gently sloping, submerged platform of a continent that extends from the shoreline to the shelf break. The continental slope is a steeper zone that descends from the shelf break to the deep ocean floor. The continental rise is the final gently sloping seafloor region at the base of the continental slope.

Continental drift - the movement of tectonic plates

When continents break apart into separate land masses, it is called continental drift. This process is driven by the movement of tectonic plates in the Earth's lithosphere.
The edge is called the shelf break. The actual declining shelf is called the called the continental slope.
