Continental margins occupy the perimeters of ocean basins where they meet the continents. Many continental margins exhibit three distinct segments: a shelf, slope, and
rise. Shelves (most landward segments) are flooded extensions of the continents. Slopes (middle segment) are steep as the name implies, and represent the approximate
boundary between oceanic and continental crust. The rise (most seaward segment) is a gradual descent to the deep basin.
Ocean basin floors consist of flat plains (called abyssal plains) dotted with seamounts and also include deep trenches. Seamounts are underwater volcanoes. Most seamounts
are extinct. Often they form at mid-ocean ridges (discussed below). Embedded in moving plates of lithosphere, seamounts migrate away from mid-ocean ridges and gradually
subside. Guyots are seamounts with flat tops, formed by waves eroding a volcano that once rose above sea level.
Ocean trenches are long narrow features of the ocean floor, which form where moving plates plunge into the mantle below. This setting is called a subduction zone. Trenche
are the deepest parts of oceans; the deepest trenches are approximately 11 km beneath sea level.
Extensive faulting and volcanic structures characterize mid-ocean ridges (sometimes called spreading centers). Plates on either side of a mid-ocean ridge spread apart from
one another. Mid-ocean ridges average about 1,300 km wide, with a 20-80 km wide central depression called the rift valley, a site of active volcanism. In some places, the
volcanoes extend above sea level to form islands such as Iceland.
