What are the relief features of the oceans?

By Ritesh|Updated : September 7th, 2022

The relief features of the oceans are mountains, basins, plateaus, ridges, canyons, and trenches. The ocean floors are rugged with the world's largest mountain ranges, deepest trenches, and largest plains.

  • These features are formed, as with continents, by factors of tectonic, volcanic, and depositional processes.
  • The central part of the ocean floor is located between 3-6 km below sea level.
  • The land beneath the ocean is the ocean floor that exhibits complex and distinct properties similar to the variants on land.

Relief Features of the Oceans

Ocean floors can be divided into four main divisions:

Continental shelf:

  • A continental shelf is a submerged part of a continent that gradually slopes towards the sea from the coast.
  • A submarine canyon is a deep valley cut into the continental shelf and extends into the continental slope.

Continental Slope:

  • The continental slope is a steeply sloping part of the seafloor that marks the boundary between the seafloor and the continental shelf.
  • A belt of sediments deposited along the base of a continental slope is called a continental slope.

Abyssal Plain:

  • They cover much of the ocean floor at a depth of 3,000 to 6,000 m.
  • These plains are covered with fine-grained sediments such as clay and silt.

Ocean depths:

  • They are long, narrow, steep, and flat depressions on the ocean floor.
  • They are generally called submarine trenches.
  • They are usually located near areas of volcanic and earthquake activity.
  • Large earthquakes and tsunamis are born in them.

Small features of ocean relief:

  • ridges,
  • Hills,
  • seamounts,
  • guys
  • ditches,
  • canyons,
  • sleeping
  • fracture zones.

Summary:

What are the relief features of the oceans?

The world's greatest mountain ranges, deepest trenches, and largest plains can be found on the rocky ocean floors. Similar to how continents are formed, these features result from tectonic, volcanic, and depositional processes.

  • Most ocean floor is found between 3 and 6 kilometers below sea level.
  • The ocean floor, which resembles variations on land in its distinctive features, is the equivalent of the ground beneath the sea.
