Identification Of 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.

Identification of features on the ocean floor.

Mid ocean ridge underwater on the sea floor that are made up of magma and run all around the ocean. The under water topography maps have been developed by the study of ocean floor topography. Beyond this slope is the abyssal plain a smooth and nearly flat area of the ocean floor. Relate features of the ocean floor to plate tectonics.

Less than one tenth of 1 of. Identify nonliving resources on or below the ocean floor. 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. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

These areas are among the flattest and least explored on the earth s surface. Identification of features on the ocean floor different oceanic features are numbered 1 through 10 adjacent to the figure below. Features of the ocean include the continental shelf slope and rise. Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only the ocean floor.

The mountain ranges of the mid ocean ridge trenches and underwater volcanoes are all formed by interactions of earth s plates. The ocean floor is called the abyssal plain. 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. The ocean floor off the continental shelf is known as the abyssal plain.

Mid ocean ridge group of underwater mountain chains criss crossing the oceans. On the sea floor made up of rocks minerals sediments and sand a steep cliff like slope increases water pressure and is where the continent connects with the ocean floor. Mean water level observed for a given duration day month year. Write the name for each feature using the choices listed below.

It is formed by an outpouring of magma. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. It is used as a reference to define coastal features and calculate the elevation of topographical elements. At the edge of the shelf the ocean floor drops off in a steep incline called the continental slope.

Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. Gives examples of living resources from the ocean floor.
