15 Which of the Following Correctly Describes Seafloor Spreading

The pattern shows that they are not the same age and are constantly moving apart. Evidence from Molten Material- Rocks from when molten material hardens quickly erupting underwater.

. A b and 14. Most of the Philippine Islands were once part of island arcs. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

This is called the theory of. Many individuals get some information about which of the following correctly describes seafloor spreading. Sea floor spreading is a process in which new ocean floor is created through volcanic activity.

This is caused by plate tectonics. Seafloor spreading is a process in which tectonic plates large irregularly shaped slabs of solid rock that is usually made up of both continental and oceanic lithosphere move and separate apart from each other. Therefore we can conclude that continental drift is related to seafloor spreading.

A and b D. The oldest seafloor can be found towards the edges of the ocean near the eastern and western continents. The magnetic patterns of the earth reverse themselves every 400 to millions of years.

New Oceanic crust is formed of tectonic plates and then spreads outward in bands. Correctly describes seafloor spreading. What did scientist use to prove the the seafloor was spreading apart.

Continental drift is also caused by plate tectonics. Seafloor spreading is caused by diverging plates. The average density of continental crust is 28 gcm 3 and the average density of oceanic crusts is 32 gcm 3.

The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. If these two plates came together what would happen.

In the early 1900 Alfred Wegener came up with a theory of continental driftIt is the idea that continents have been shifting positions on the earths surface over time and in 1960s Henry Hess proved Wegeners idea right. Which of the following correctly describes seafloor spreading. Science 6 Inside Earth Convection and Mantle.

Seafloor near the Mid-Atlantic ridge plate tectonic boundary can be up to 10 million years old. Seafloor spreading occurs when rising magma generates new ocean seafloor at ridges and pushes plates apart which causes old seafloor to be destroyed where it. Seafloor spreading occurs along mid-ocean ridgeslarge mountain ranges rising from the ocean floor.

Which of the following correctly describes seafloor spreading. Seafloor spreading is a geologic process in which tectonic plateslarge slabs of Earths lithospheresplit apart from each other. Evidence from Magnetic Stripes- Scientists discovered that the rock that makes up the ocean floor lies in a pattern of magnetized stripes.

The two plates would push apart and form a rift zone. Which of the following correctly describes seafloor spreading. New oceanic crust is formed at seamounts and spreads outward in all directions.

New oceanic crust is formed at seamounts and spreads outward all directions. New oceanic crust is formed at mid ocean ridges pushed away from the ridge and destroyed at deep-sea trenches is the correct statement Option B Seafloor spreading is a process that occurs at the mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge and then are destroyed at the. New oceanic crust is formed at midocean ridges pushed away from the ridge and destroyed at deep-sea trenches.

New oceanic crust is formed at midocean ridges pushed away from the ridge and destroyed at deep-sea trenches. This theory introduced by Harry Hess was proven as patterns of magnetic. A process that occurs at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

How does magnetic reversion show evidence of seafloor spreading. В 13 Earthquake as an effect of plate movement results in boundaries where plates are a converging b. Seafloor spreading is caused by two plates moving apart.

When the plates move it carries the continents with it and thus the continents drift away from each other. It is the new maritime outside layer that structures through springs of gushing lava emission and after some time they get away from the edge. Sea floor spreading occurs at the divergent.

New oceanic crust is formed at deep-sea trenches pushed away from the trench and destroyed at midocean ridges. New oceanic crust is formed at midocean ridges pushed away from the ridge and destroyed at deep-sea trenches. The oceanic plate would rise up over the continental plate.

Log in for more information. Mantle convection is the slow churning motion of Earths mantle. Sets with similar terms.

Seafloor spreading is the mechanism by which new seafloor lithosphere is constantly being created at mid-ocean ridges. Seafloor spreading is an interaction that will happen at the edges of the mid-sea. In a process taking tens of millions of years part of the ocean floor sinks back into the mantle at deep-ocean trenches.

The lithosphere is divided into 7 plates that once were one super continent called Pangea. The Mid-Atlantic Ridge for instance separates the North American plate from the Eurasian plate and the South American plate from the African plate. The youngest sea floor can be found towards the edges of the ocean near the eastern and western continents.
