Geological Features On The Ocean Floor

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

Geological features on the ocean floor.

Features of the ocean include the continental shelf slope and rise. However the ocean floor is not flat. The abyssal plain has a depth between 2 200 and 5 500 m 7 200 and 18 000 ft and covers about 40 of the ocean floor. At the ocean ridges such as the mid atlantic ridge the plates are moving apart which is.

It has a wide variety of geological features e g fig. The ocean floor off the continental shelf is known as the abyssal plain. There are many geologic features on the ocean floor. Less than one tenth of 1 of.

Volcanic eruptions and earthquakes are also the result of tectonic plate movement. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. What are three. Trenches ridges rises and islands are the result of continental or oceanic plate movement.

It is used as a reference to define coastal features and calculate the elevation of topographical elements. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Geologic activity around the plate boundaries on the ocean floor provide evidence of plate tectonics. The ocean floor is called the abyssal plain.

Below the ocean floor there are a few small deeper areas called ocean trenches. These areas are among the flattest and least explored on the earth s surface. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. Navigators of ships and submarines are interested in avoiding dangers or impediments to their progress.

Mean water level observed for a given duration day month year. Mid ocean ridge group of underwater mountain chains criss crossing the oceans. It is formed by an outpouring of magma.
