What Is The Most Important Topographic Feature Of The Ocean Floor Why?

The vital features are the wide continental cabinets under 250 m deep (pink); the vast deep ocean plains between 4,000 and 6,000 m deep (light and dark blue); the mid-Atlantic ridge, in lots of areas shallower than 3,000 m; and the deep ocean trench north of Puerto Rico (8,600 m).

The important features are the extensive continental shelves less than 250 m deep (pink); the vast deep ocean plains between 4,000 and 6,000 m deep (light and dark blue); the mid-Atlantic ridge, in many areas shallower than 3,000 m; and the deep ocean trench north of Puerto Rico (8,600 m).

What is the ocean floor topography?


How does the age of the sea floor support sea-floor spreading?

The age of the ocean-floor also helps sea-floor spreading. If sea-floor spreading operates, the youngest oceanic crust should be found at the ridges and progressively older crust can be found in moving away from the ridges towards the continents. This is the case.

What is the difference between seafloor spreading and convection?

Vocabulary. Seafloor spreading is a geologic system by which tectonic plate s—large slabs of Earth’s lithosphere —split aside from one another. Seafloor spreading and other tectonic pastime processes are the results of mantle convection. Mantle convection is the slow, churn ing motion of Earth’s mantle.

What do the maps tell us about the seafloor?

And better of all, which you could explore the maps for yourself! Above: A marine gravity map of the North Atlantic Ocean Red dots show destinations of earthquakes with magnitude > 5.5 and that they highlight the existing-day vicinity of the seafloor spreading ridges and seriously change faults.

How does topography of the seafloor give evidence for seafloor spreading?

Abundant proof helps the main contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become gradually more youthful as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.

How do seafloor spreading and ridges affect sea level?

Mid-ocean ridges and seafloor spreading also can influence sea level s. As oceanic crust moves clear of the shallow mid-ocean ridges, it cools and sinks as it turns into more dense. This increases the amount of the ocean basin and decreases the sea level.

How is seafloor spreading related to the thickness of the crust?

The age, density, and thickness of oceanic crust raises with distance from the mid-ocean ridge. The magnetism of mid-ocean ridges helped scientists first determine the system of seafloor spreading in the early 20th century.

What is seafloor spreading and why is it important?

Seafloor spreading ends up in the renewal of the sea floor in every 200 million years, a period of time for building a mid-ocean ridge, moving away around the ocean and subduction into a trench. The highly dense oceanic crust that is formed after a progressive spreading is destined to two possible occurrences.

What are the main features of seafloor spreading?

Seafloor spreading produces major characteristics of the seafloor – 1) the age of the seafloor is progressively older away from midocean ridges, 2) the elevation of the seafloor is steadily lower away from midocean ridges, 3) the magnetic history of the seafloor bears the striped-pattern of the Earth’s magnetic …

What is the topography of the seafloor?

The term “topography” implies the study of numerous landforms that exist on or below the earth. Ocean floor topography refers to the various forms by which the ocean floor bottom can exist. You may understand the sea floor to be flat and sandy like the beach, but the truth is there are many different surfaces.

Which of the following are features of seafloor topography?

Features of the ocean floor come with the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge. The ocean floor is rich in supplies. Living things on the ocean floor are used for food or drug treatments.

What is seafloor spreading in geology?

The earth’s crust is broken into large slabs called tectonic plates. The plates are in slow persistent circulate. The seafloor spreading definition is the geologic technique that occurs at the boundary among 2 plates where molten fabric within the earth pushes its way up, inflicting the plates to move away from one another.

What do you put on a tuna casserole?
