What is ocean floor relief?

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 4 types of ocean floor?

Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge. The ocean floor is rich in resources. Living things on the ocean floor are used for food or medicines.

What is oceanic ooze?

Oozes are basically deposits of soft mud on the ocean floor. They form on areas of the seafloor distant enough from land so that the slow but steady deposition of dead microorganisms from overlying waters is not obscured by sediments washed from the land.

What are the different types of oozes on the seafloor?

There are two types of oozes, calcareous ooze and siliceous ooze. Calcareous ooze, the most abundant of all biogenous sediments, comes from organisms whose shells (also called tests) are calcium-based, such as those of foraminifera, a type of zooplankton.

Which are the main factors that affect ocean relief?

Ocean relief is largely due to tectonic, volcanic, erosional and depositional processes and their interactions….Four major divisions in the ocean relief are:

• the continental shelf,
• the continental slope,
• the continental rise,
• the Deep Sea Plain or the abyssal plain.

What are the main features 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.

What are the 3 basic types of ocean floor?

There are three kinds of sea floor sediment: terrigenous, pelagic, and hydrogenous. Terrigenous sediment is derived from land and usually deposited on the continental shelf, continental rise, and abyssal plain.

Does siliceous ooze dissolve?

Siliceous ooze dissolves slowly in cold water and rapidly in warm water. can dissolve them and thus prevent them from reaching and building up on the ocean floor.

What produces siliceous ooze?

Siliceous oozes are largely composed of the silica based skeletons of microscopic marine organisms such as diatoms and radiolarians. Other components of siliceous oozes near continental margins may include terrestrially derived silica particles and sponge spicules.

What is it called when siliceous ooze Lithifies?

Diatomaceous Earth • Siliceous ooze lithifies into diatomaceous earth. • Diatomaceous earth. has many. commercial uses.

What are the 3 types of ocean currents?

Oceanic currents are driven by three main factors:

• The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast.
• Wind. Winds drive currents that are at or near the ocean’s surface.
• Thermohaline circulation.

What are the major relief features?

The Major Physiographic divisions of India : The relief divisions of India landmass can be divided in to the following groups.

• The Himalayas.
• The Indo – Gangetic plain.
• The Peninsular plateau.
• The coastal plains.
• The Desert (The Thar)
• The Islands.

What are the relief features of the ocean floor?

8.2 THE RELIEF OF THE OCEAN BASINS The ocean water conceals a considerable variety of landscape very similar to its counterpart on the continents. 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 is the meaning of the term ocean relief?

Ocean relief is the outcome of the great depressions of the earth’s outer layer mostly on the bottom surface. The bottom surface of the ocean or known as ‘land’ under the waters of the ocean floor creating the complex and varied features. ads. As a result, there are deepest trenches and the largest plains on the ocean floor as well.

How is Ocean relief related to the Great Depression?

Ocean relief is the outcome of the great depressions of the earth’s outer layer mostly on the bottom surface. The bottom surface of the ocean or known as ‘land’ under the waters of the ocean floor creating the complex and varied features. As a result, there are deepest trenches and the largest plains on the ocean floor as well.

Are there submarine relief features in the ocean?

The ocean water conceals a considerable variety of landscape very similar to its counterpart on the continents. 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.
