What Are The 3 Regions Of The Ocean Floor

The ocean floor or seabed can be divided into three major regions.

What are the 3 regions of the ocean floor.

The continental margins abyssal plains and mid ocean ridges. Running through all the world s oceans is a continuous mountain range called the mid ocean ridge submarine ridge in figure 14 23. What are the three major regions of the ocean floor and some features associated with each region. This region has very little volcanic or earthquake activity.

The three major regions of the ocean floor is the continental margin the deep ocean basin and the ocean floor. 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. 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. How do continental margins in the atlantic ocean differ from those in the pacific ocean.

Continental shelf is the shallow portion of the ocean which lies close to the continental margin. The smooth flat regions that make up 40 of the ocean floor are the abyssal plain. In the atlantic ocean thick layers of undisturbed sediment cover the continental margin. 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.

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. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. The ocean floor regions are the continental margins the ocean basin floor and the mid ocean ridge.

In general the ocean floor can be divided into four major divisions. The first major distinction is between the pelagic and benthic zones.
