Continental margins are the zones where the continents meet the ocean. They consist of the continental shelf, continental slope, and continental rise. The continental shelf is a gently sloping area that extends from the shore to the deeper ocean, while the continental slope is a steeper incline leading down to the ocean floor. The continental rise is formed by sediments that accumulate at the base of the slope. These margins are important for various reasons, including their role in marine ecosystems and their potential for natural resources. They often contain rich fishing grounds and can be sites for oil and gas exploration. Understanding continental margins helps scientists study geological processes and oceanic life.
