What kind of features are found on the ocean floor?

Like dry land, the ocean floor has various features including flat plains, sharp mountains, and rugged canyons (Fig. 7.1). However, the lowest point in the world ocean is much deeper than the highest point on land. The ocean floor is continually being formed and destroyed.

What are the three features of the ocean floor?

Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain.

What are the main features of the deep sea floor?

The bottom of the deep sea has several features that contribute to the diversity of this habitat. The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps. Carcasses of large animals also contribute to habitat diversity.

What are the six features of the ocean floor?

There are nine main features of the ocean floor which include (1) continental shelf, (2) continental slope, (3) continental rise, (4) abyssal plains, (5) abyssal hill, (6) mid-ocean ridges, (7) seamounts, (8) deep ocean trenches, and (9) volcanic islands.

What is the unique feature of the oceanic crust?

Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition. Like continental crust, however, oceanic crust is destroyed in subduction zones. The lavas are generally of two types: pillow lavas and sheet flows.

What are the most prominent features on the ocean floor quizlet?

Terms in this set (7)

  • Abyssal plain. An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m.
  • Continental shelf.
  • continental slope.
  • Med-oceans ridge.
  • Oceanic trench.
  • Seamount.
  • Sonar.

What are the parts of oceanic crust?

Not including a sedimentary cover of variable thickness and composition, the oceanic crust consists of three layers: (1) a relatively thin uppermost volcanic layer of basaltic lavas known as mid-ocean ridge basalts (MORB) erupted on the seafloor; (2) a thicker layer of more coarsely crystalline, intrusive basaltic …

What is the most prominent feature on the ocean floor?

oceanic ridges
oceanic ridge, any of several continuous submarine mountain chains rising from the ocean floor. Individually, oceanic ridges are the largest features in ocean basins.

What are the relief features of ocean floor?

Oceanic land-forms (submarine relief) There are mountains, basins, plateaus, ridges, canyons and trenches beneath the ocean water too. These relief features found on the ocean floor are called Submarine Relief.

What are the prominent features of the ocean floor?

Trenches are the deepest parts of the oceans.

  • The trenches are comparatively steep-sided and have narrow basins.
  • They are some 3-5 km deeper than the adjacent ocean floor.
  • They are found at the bases of continental slopes and along island arcs
  • Trenches are associated with active volcanoes and strong earthquakes.

    • What feature is not found on the ocean floor?

    The broad size of the ocean floor, its depth and its combination of extreme conditions (cold, dark, with intense water pressure) all contribute to making its exploration difficult. Early civilizations believed the ocean floor to be a smooth bowl, devoid of features or life.

    Which is not a feature found on the ocean floor?

    The ocean floor is not a flat, featureless surface. Plate tectonic theory is useful in understanding many features of the ocean floor. The Atlantic and Pacific Ocean floors are very different in terms of size and features. The features one would encounter crossing the Atlantic Ocean floor.

    What are the characteristics of the ocean floor?

    Abyssal plain. An abyssal plain is an underwater plain on the deep ocean floor,usually found at depths between 3000 and 6000 m.

  • Continental shelf.
  • continental slope.
  • Med-oceans ridge.
  • Oceanic trench.
  • Seamount.
  • Sonar. How do ocean floor features form? Bathymetry,the shape of the ocean floor,is largely a result of a process called plate tectonics.
