Identification Of Features On The Ocean Floor

It is used as a reference to define coastal features and calculate the elevation of topographical elements.

Identification of features on the ocean floor. The under water topography maps have been developed by the study of ocean floor topography. Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only 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. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

The ocean floor is called the abyssal plain. Mid ocean ridge underwater on the sea floor that are made up of magma and run all around the ocean. 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. Relate features of the ocean floor to plate tectonics.

Beyond this slope is the abyssal plain a smooth and nearly flat area of the ocean floor. These areas are among the flattest and least explored on the earth s surface. The mountain ranges of the mid ocean ridge trenches and underwater volcanoes are all formed by interactions of earth s plates. Features of the ocean include the continental shelf slope and rise.

Gives examples of living resources from the ocean floor. Identify nonliving resources on or below the ocean floor. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. Mid ocean ridge group of underwater mountain chains criss crossing the oceans.

Create a diagram to show how sonar is used to find the distance from the surface to the ocean floor. Mean water level observed for a given duration day month year. The ocean floor off the continental shelf is known as the abyssal plain. Identification of features on the ocean floor different oceanic features are numbered 1 through 10 adjacent to the figure below.

Note that the lettered spaces below do not correspond exactly to the numbered descriptions in the textbook. Less than one tenth of 1 of. It is formed by an outpouring of magma. Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops.
