3 Major Topographic Units Ocean Floor

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. By the late 1940 s and 1950 s use of the echo sounder had allowed oceanographers to put together a pretty complete picture of the topography of the ocean floor. Be careful when interpreting this diagram and others like it because in order to show the various features clearly the vertical axis is exaggerated in this case by about 200 times.

The under water topography maps have been developed by the study of ocean floor topography.

3 major topographic units ocean floor.

Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. Continental margins ocean basin floor oceanic mid ocean ridge. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. Oceanic ridges continental margins and deep ocean basins how can satellites orbiting earth determine features on the seafloor without being able to directly observe them beneath several kilometers of seawater.

Major topographic divisions of 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. Three major divisions 1. The reason is that large structures like seamounts attract water by 2 causing the sea surface to be slightly higher where the depth is shallower continental margins ocean basin floor mid ocean ridge three major topographic units of the ocean floor.

A topographic profile of the pacific ocean floor between japan and british columbia is shown in figure 18 3. Where are passive continental boundaries located. What are the three major topographic units of the ocean floor. Features that make up a passive continental margin.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Continental margins deep ocean basins and mid ocean ridges. Experience little volcanism and few earthquakes. Found along most coastal areas that surround the atlantic ocean.

Three major topographic units of the ocean floor. What are the three major topographic provinces of the ocean floor. What are the three primary topographic profiles of the ocean floor. Found along most coastal areas that surround the atlantic ocean.

Passive continental margins are found where. The three major regions of the ocean floor is the continental margin the deep ocean basin and the ocean floor. 3 major topographic units of the ocean floor.
