Identification Of Features On The Ocean Floor

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.

Identification of features on the ocean floor.

Create a diagram to show how sonar is used to find the distance from the surface to the ocean floor. 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. It is used as a reference to define coastal features and calculate the elevation of topographical elements.

Gives examples of living resources from the ocean floor. Note that the lettered spaces below do not correspond exactly to the numbered descriptions in the textbook. The ocean floor is called the abyssal plain. The under water topography maps have been developed by the study of ocean floor topography.

Identify nonliving resources on or below the ocean floor. The ocean floor off the continental shelf is known as 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. Identification of features on the ocean floor different oceanic features are numbered 1 through 10 adjacent to the figure below.

Mid ocean ridge group of underwater mountain chains criss crossing the oceans. It is formed by an outpouring of magma. The mountain ranges of the mid ocean ridge trenches and underwater volcanoes are all formed by interactions of earth s plates. Mean water level observed for a given duration day month year.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Less than one tenth of 1 of. Features of the ocean include the continental shelf slope and rise. Relate features of the ocean floor to plate tectonics.

These areas are among the flattest and least explored on the earth s surface. At the edge of the shelf the ocean floor drops off in a steep incline called the continental slope. Mid ocean ridge underwater on the sea floor that are made up of magma and run all around the ocean. 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.

Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth.
