What are 4 types of ocean floor?

What are 4 types 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.

How are the ocean floor characteristics similar to land features?

The ocean floor covers more than 70 percent of the planet’s surface. 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.

What is ocean and its features?

The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into four distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans.

What are five ocean floor features?

Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge.

What is another name for the deep ocean floor?

The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean.

What are major geological features of the ocean floor?

There are many geologic features on the ocean floor. Trenches, ridges, rises, and islands are the result of continental or oceanic plate movement. Volcanic eruptions and earthquakes are also the result of tectonic plate movement.

What are the relief features of ocean?

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….They are;

• Continental Shelf.
• Continental slope.
• Abyssal plains.
• The ocean deeps/ submarine trenches.

What are the main features of ocean?

The Many Features of our Oceans

• 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 are the features of an ocean habitat?

Some habitats are shallow, sunny and warm. Others are deep, dark and cold. Plant and animal species are able to adapt to certain habitat conditions, including movement of water, amount of light, temperature, water pressure, nutrients, availability of food, and saltiness of water.

What is the ocean floor called?

abyssal plain
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 are the most prominent features on the ocean floor?

Though hidden beneath the ocean surface, the global mid-ocean ridge system is the most prominent topographic feature on the surface of our planet.

What is at the very bottom of the ocean?

At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth. Challenger Deep is the deepest point of the Marianas Trench. The Sirena Deep is the second-deepest part.

What causes subduction and seafloor spreading?

Subduction occur when two plates converge towards each other and the denser plate being heavier slide below the lighter plate and Sea floor spreading occur at the Mid oceanic ridges where Diverging limbs of Convection cells tend to pull apart the plate and create a Rift Valley like the East African rift valley .

What is the evidence for seafloor spreading?

Molten materials and magnetic stripes are the evidence of seafloor spreading. When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading.

What are facts about seafloor spreading?

What Happens During the Process of Seafloor Spreading? History. Scientists originally believed that drifting was an occurrence exclusive to continents through continental drifts. Geographic Features. The process of seafloor spreading leads to the formation of numerous geographical features which can be terrestrial, sub-terrestrial, or marine features. Mid-Ocean Ridges.

What is the depth of the sea floor?

In most of the world, the ocean floor is very deep, averaging 3,790 meters (12,430 ft) in depth. Nearly half of the world’s sea floors are over 3,000 meters (9,800 ft) deep. Altogether, the deep sea floor makes up about 71% of the world’s oceans, with shallow waters, such as continental shelves, making up 29%.
