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 three major regions of the ocean floor is the continental margin the deep ocean basin and the ocean floor. The smooth flat regions that make up 40 of the ocean floor are the abyssal plain. What are the three major regions of the ocean floor and some features associated with each region. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
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. This region has very little volcanic or earthquake activity. 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. Sediments in tectonically active regions are other thrust slices of ocean floor deposits.
Continental shelf is the shallow portion of the ocean which lies close to the continental margin. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Running through all the world s oceans is a continuous mountain range called the mid ocean ridge submarine ridge in figure 14 23. In general the ocean floor can be divided into four major divisions.
It is actually a part of the continent sloping gently towards the. The first major distinction is between the pelagic and benthic zones. How do continental margins in the atlantic ocean differ from those in the pacific ocean. The ocean floor regions are the continental margins the ocean basin floor and the mid ocean ridge.
In the atlantic ocean thick layers of undisturbed sediment cover the continental margin. The continental margins abyssal plains and mid ocean ridges.
