What are the 3 features of the ocean basin 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. …

What are the 3 parts of the ocean basin?
The ocean floor or seabed can be divided into three major regions: the continental margins abyssal plains and mid-ocean ridges. These regions are easily distinguished by topographical characteristics.
What is a deep ocean basin quizlet?
deep ocean basin. The part of the ocean floor that is under deep water beyond the continental margin and that is composed of oceanic crust and a thin layer of sediment.
What are the 5 different structures of the ocean basin?
There are five major subdivisions of the world ocean: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean.
Which of the following features would you find in an ocean basin?
1 Answer. Ocean ridges, deep-sea trenches, abyssal hills, fracture zones, seamounts, and guyots are some of the major features of an ocean basin.

What is a flat region of deep ocean basins?
Abyssal plain: Flat or very gently sloping area of the deep ocean basin floor.
What are the 4 major ocean basins?
Even though there is one world ocean, it has traditionally been divided into four major ocean basins: the Arctic, the Atlantic, the Indian, and the Pacific.
What are the features of ocean?
Features of the Ocean
- Intertidal or Littoral – located from high tide to low tide areas. …
- Continental shelf – located from low tide to the edge of the shelf.
- Continental slope – where the ocean bottom slopes steeply to the ocean floor.
- Abyssal plane – the 'bottom' of the ocean where it is relatively flat.
What is the structure of ocean basins?
The first layer consists mostly of sediments overlying the igneous crust of the second and third layers. The second layer is volcanic, dominated by pillow lavas and other types of basaltic lavas (above) and basaltic dykes (below), and the third layer is gabbro and represents magma that has crystallized at depth.
What are the 8 features of the ocean floor?
What are the eight main features of the ocean floor? Continental shelf, continental slope, continental rise, abyssal plain, mid-ocean ridge, ocean trench, seamount, and volcanic island. What is a continental shelf? An underwater plain between a continent and the deep ocean that slowly slopes.
What are the ocean features?
The sonar showed that the ocean floor has dramatic physical features, including huge mountains, deep canyons, steep cliffs, and wide plains. The ocean's crust is a thin layer of volcanic rock called basalt. The ocean floor is divided into several different areas.
What are common to all features of ocean basin structure?
Yet, they all contain certain common features such as oceanic ridges, trenches, and fracture zones and cracks, abyssal plains and hills, seamounts and guyots.
How do modern ocean basins form?
Plates can spread apart by moving away from each other. This creates gaps where hot molten rock, called magma, from the earth's mantle can rise up. When the magma seeps through the gaps, it solidifies as it cools, creating a new layer of ocean crust.
What are the four stages of the evolution of an ocean basin from first to last quizlet?
1) The upper crust is broken along normal faults while the lower crust is deformed by ductile stretching; (2) tension pulls apart the crusts and crust slab sink in the middle, forming a rift valley; (3) continued spreading creates a narrow sea; (4) after continued spreading, an ocean and ridge system are created.
What are common in features of ocean basin structure?
Yet, they all contain certain common features such as oceanic ridges, trenches, and fracture zones and cracks, abyssal plains and hills, seamounts and guyots.
What are five features of the ocean?
Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge.
What are the landforms of the ocean basin?
Landforms under the ocean are:
- continental shelf,
- continental slope,
- continental rise,
- abyssal plain,
- mid-ocean ridge,

- seamount/guyot.
What are the four stages of formation of an ocean basin?
Wilson cycle
- Embryonic Ocean Basin (Stable Craton with a hot spot underneath) Stage A: …
- Juvenile Ocean Basin (Early Rifting of a Continent) Stage B: …
- Mature Ocean Basin (Full ocean basin) Stage C: …
- Declining ocean basin (Subduction Zone) Stage D: …
- Terminal Ocean Basin (Closing Remnant Ocean Basin) Stage E:
What are the 6 stages of the evolution of ocean basins?
A Wilson cycle consists of six stages: embryonic, juvenile, mature, declining, terminal, and suturing. The cycle begins because thick continental crust does not conduct heat as readily as thinner oceanic crust.

Which of the following is are result’s in the creation of many ocean basins features?
So, an area of the world that is tectonically active, whether it be on land or under the water, would be a mountainous area with earthquakes and volcanic activity. This creates many of the ocean basins features.
