What is the continental shelf?
Quick Answer
The continental shelf is the shallow underwater edge of a continent that extends from the shoreline to the point where the seafloor drops off steeply. It is usually covered by relatively shallow seas.
The Full Story
The continental shelf is the submerged extension of a continent, beginning at the coast and ending at the shelf break, where the slope descends toward the deep ocean. Its width can vary greatly: in some places it is narrow, while in others it stretches for hundreds of kilometers. Because sunlight reaches it, the continental shelf is often rich in marine life and supports major fisheries. It also contains important oil and gas reserves in many regions. Geologically, it is considered part of the continent rather than the deep-ocean floor.
