Ocean Floor Features

In the pacific ocean occeanic crust is plunging beneath the continental crust.

Ocean floor features. Features rising up from the ocean floor include seamounts volcanic islands and the mid oceanic ridges and rises. Science has established that the topography of the ocean floor is similar to the ground topography with features such as valleys mountains and plateaus. This feature is thought to be part of the eurasian continental crust that rifted from the barents kara sea margin and subsided in early tertiary time about 64 to 56 million years ago.

Continental margin and oceanic divisions. Further ocean floor features most of the remaining features of the ocean floor result from large outpourings of magma which typically form submarine volcanoes. Many ocean floor features are a result of the interactions that occur at the edges of these plates.

This product is intended to aid fishermen and those needing seafloor features and potential fishing grounds. Features of the ocean include the continental shelf slope and rise. These areas are among the flattest and least explored on the earth s surface.

Three quarters of the earth consists of ocean water. The ocean floor is called the abyssal plain. 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. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches. 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.

The dominant topographic feature of the arctic ocean seafloor is the lomonosov ridge. Underwater on the sea floor that are made up of magma and run all around the ocean. All these details are incorporated on underwater topography maps.
