What are the features of Ocean basin?

What are the features of Ocean basin?

A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots.

What are the 3 features of the ocean basin floor?

The sea floor can be subdivided into three major features: (1) continental margin, (2) abyssal plain, and (3) Mid-Atlantic Ridge. The continental margin is itself comprised of the shelf, slope and rise. The margin is the portion adjacent to the continent and the transition to the deep ocean basin.

What are the Earth’s 4 ocean basins?

Ocean Basins

• Pacific Ocean Basin.
• Atlantic Ocean Basin.
• Indian Ocean Basin.
• Southern Ocean.
• Arctic Ocean Basin.

Which feature of the ocean floor includes its deepest parts?

The deepest parts of the ocean are within the subduction trenches, and the deepest of these is the Marianas Trench in the southwestern Pacific (near Guam) at 11,000 m (Figure 18.5).

What does the deep ocean basin consist of?

Deep-ocean basins cover the greatest portion of the Earth’s surface. Geographic features associated with deep-ocean basins include trenches, abyssal plains, ocean ridges and rises, and submarine mountainous regions.

How did ocean basins evolve what are its feature?

Active ocean basins undergo change mainly due to plate tectonics. Plate tectonics is the theory used to explain the dynamics of the earth’s surface resulting from the interaction of the overlying rigid plates with the underlying mantle. According to the theory, the earth has a rigid outer layer called the crust.

What are the physical features of the ocean called?

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 geologic features are found in ocean basins?

The ocean basins contain many extraordinary geological features, including deep trenches and vast mountain ranges. A continental margin is a part of the ocean basin that is adjacent to a continent. It includes the continental shelf, a sloping section of material that lies on top of continental crust.

What are the characteristics of the Indian Ocean?

Indian Ocean: Ocean basins. Ocean basins are characterized by smooth, flat plains of thick sediment with abyssal hills (i.e., features that are less than 3,300 feet high) at the bottom flanks of the oceanic ridges.

What are the different types of underwater landforms?

Underwater landforms. 1 Continental shelf. Starting from land, a trip across an ocean basin along the seafloor would begin with crossing the continental shelf. The 2 Abyssal plains. 3 Mid-ocean ridge. 4 Ocean trenches. 5 Plate tectonics and the ocean floor.

What are the floors of the oceans like?

The floors of our world’s oceans contain features that you might recognize as being similar to some structures on land. In this lesson, you will learn about these features, including undersea mountains and trenches and how they are formed. Are you a student or a teacher?
