Structure of the Ocean Floor
The ocean floor has varied features like continental shelves, slopes, abyssal plains, and trenches, each with distinct characteristics.
Core concept
The continental shelf is a gently sloping, shallow extension of a continent under water, rich in marine life and resources.
How it works
The continental slope descends more steeply from the shelf to the deep ocean floor, marking the edge of the continent.
Why it matters
The abyssal plain is a flat, deep area of the ocean floor, covering large stretches of the deep ocean.
Key detail
Ocean trenches are the deepest parts of the ocean, formed where tectonic plates collide, like the Mariana Trench.
