What Are The 3 Regions Of The Ocean Floor

Sediments in tectonically active regions are other thrust slices of ocean floor deposits.

What are the 3 regions of the ocean floor.

The ocean floor regions are the continental margins the ocean basin floor and the mid ocean ridge. The first major distinction is between the pelagic and benthic zones. 1 3 marine provinces in section 1 2 we learned about the regions that make up the continental margins so before we leave this topic we will look at some of the other ways we can categorize the ocean environments. How do continental margins in the atlantic ocean differ from those in the pacific ocean.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. In the atlantic ocean thick layers of undisturbed sediment cover the continental margin. These are thinner about 0 5 km 0 3 mi thick or less and are characterized by radiolarian rich cherts basaltic volcanic dikes sills and submarine lava flows as well as silts and clays of the distal ends of turbidity flows. The continental margins abyssal plains and mid ocean ridges.

This region has very little volcanic or earthquake activity. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The three major regions of the ocean floor is the continental margin the deep ocean basin and the ocean floor. Continental shelf is the shallow portion of the ocean which lies close to the continental margin.

In general the ocean floor can be divided into four major divisions. What are the three major regions of the ocean floor and some features associated with each region. Continental margins portion of the seaflo0r adjacent to major landmasses may include the continental shelf the continental slope and the continental rise deep ocean basins. Running through all the world s oceans is a continuous mountain range called the mid ocean ridge submarine ridge in figure 14 23.

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. It is actually a part of the continent sloping gently towards the.
