What are the 3 parts of the ocean floor describe them?

They are also shown in Figure below.

  • The continental shelf is the ocean floor nearest the edges of continents.
  • The continental slope lies between the continental shelf and the abyssal plain.
  • The abyssal plain forms much of the floor under the open ocean.
  • An oceanic trench is a deep canyon on the ocean floor.

Which section of the ocean floor is near the coastlines?

A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope. Even though they are underwater, continental shelves are part of the continent.

What are the three main provinces of the ocean floor?

Physiography and bathymetry (submarine landscape) allow the sea floor to be subdivided into three distinct provinces: (1) continental margins, (2) deep ocean basins and (3) mid-oceanic ridges.

What are 4 types of ocean floor?

Underwater landforms

  • Continental shelf. Starting from land, a trip across an ocean basin along the seafloor would begin with crossing the continental shelf.
  • Abyssal plains. Continuing your journey across the ocean basin, you would descend the steep continental slope to the abyssal plain.
  • Mid-ocean ridge.
  • Ocean trenches.

How would you describe the ocean floor?

The ocean floor is literally the floor of the ocean. The landscape of the ocean floor is much like what you see on land, just way more dramatic and without all that life. You’ll see underwater mountains called seamounts, cliffs, trenches, and abysses. These are so deep that no sunlight penetrates.

What are the major parts of the ocean floor?

Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

What’s at the bottom of the ocean floor?

Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

What feature of the ocean floor includes its deepest parts?

deep-sea trenches
It closely resembles the surface of the moon with its features such as the abyssal plain, deep-sea trenches, and seamounts. The abyssal plain is the flat, deep ocean floor. A thick layer of sediment that covers the hills and valleys found in it. Deep-sea trenches are the deepest parts of the ocean.

What are the three major regions of the ocean floor quizlet?

What are the three main regions of the ocean floor? The ocean floor regions are the continental margins, the ocean basin floor, and the mid-ocean ridge.

How many parts are there in the ocean floor?

What is the parts of the ocean?

Although the ocean is one continuous body of water, oceanographers have divided it into four principal areas: the Pacific, Atlantic, Indian, and Arctic Oceans. The Atlantic, Indian, and Pacific Oceans merge into icy waters around Antarctica.

What is the structure of the ocean floor?

What are the four parts of the ocean floor?

There are four parts of the ocean floor. The four parts are the continental shelf, continental slope, continental rise, and the abyssal plains. 1. The continental shelf is the part of the ocean floor that is a long plain beginning at the shore line which stretches towards the ocean.

What are the 5 deepest parts of the ocean?

The 5 Deepest Parts of the Ocean 5. Kermadec Trench: 32,963 ft Deep 4. Kuril-Kamchatka Trench: 34,587 ft Deep 3. Philippine Trench: 34,596 ft Deep 2. Tonga Trench: 35,702 ft Deep 1. Mariana Trench: 36,201 ft Deep

Where are the oldest parts of the oceanic crust found?

The oldest parts of the oceanic crust are found farest from the mid ocean ridges at subduction zones and continental shelves. New ocean crust is formed at the mid ocean ridges.

What is the relationship between ocean crust and ocean ridges?

New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust is. The oldest crust is at edges of the ocean.
