At which type of boundary is seafloor destroyed?

At which type of boundary is seafloor destroyed?

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Where is sea floor destroyed?

subduction zones
You are correct that the seafloor is destroyed at subduction zones, but it is simultaneously being created at mid-ocean ridges. see figure 1 . Figure 1: Seafloor spreading at a mid-ocean ridge(where new crust is being created) and it’s destruction at a subduction zone.

At which of the above boundaries is crust destroyed?

Convergent boundaries
Convergent boundaries — where crust is destroyed as one plate dives under another.

What boundaries create the sea floor?

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

What is ocean-ocean convergent boundary?

At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or subducted, under the other (Figure 4.6. 1). It mixes with the overlying mantle, and the addition of water to the hot mantle lowers the crust’s melting point and leads to the formation of magma (flux melting).

At which of the above boundaries can produce volcanoes?

The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another.

Which of the above boundaries can produce volcanoes?

Which of the above boundaries can generate tsunamis?

The correct answer is A. Convergent boundaries, where ocean plates are subducted at trenches, produce the most tsunamis because they produce the largest earthquakes.

Which plate boundary is destructive?

convergent
A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes.

Which type of plate boundary is destructive?

Convergent plate boundaries
Convergent plate boundaries A convergent plate boundary also known as a destructive plate boundary , usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes and volcanoes.

What happens at Oceanic to oceanic convergent boundary?

What destroys Earth’s crust?

Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.

What type of plate boundary is seaweed seafloor created at?

Seafloor is created at divergent plate boundaries called the mid-ocean ridges. What kind of plate boundary does seafloor spreading occur on? Seafloor spreading occurs at divergent plate boundaries under the ocean.

Is the seafloor created at a convergent or divergent boundary?

At a convergent boundary. if seafloor is created at a divergent boundary then it must be the opposite (at a convergent boundary) where is being destroyed. Wiki User ∙ 2010-12-08 01:06:31

What happens at a divergent plate boundary in the ocean?

At a divergent plate boundary between two oceanic crusts upwelling magma creates new seafloor. This newly created seafloor is largely made of basalt. At a divergent boundary land is gained or lost? At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading.

What type of crust is destroyed at a convergent boundary?

Oceanic crust is destroyed at a convergent boundary where subduction occurs. An example includes the boundary between the Nazca and South American plate on the west coast South America. Is new crust created at a convergent boundary?
