What region of the continental margin defines the edge of the continent quizlet?
The submerged outer edge of a continent is called the continental margin. The deep seafloor beyond the continental margin is properly called the ocean basin.
What is the slope between the outer edge of the continental shelf?
A continental shelf typically extends from the coast to depths of 100–200 metres (330–660 feet). It is gently inclined seaward at an average slope of about 0.1°. In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break.
Which of the following is part of the continental margin?
The continental rise, continental slope, and continental shelf are the three basic components that actually make the entire structure of continental margins. The continental slopes and the continental shelves are structural constituents of continents even though they are below the surface of sea.
