  • spreading: rock rises upward then spreads outward.
  • subduction: rock moves inward then subducts downward under lighter rock.

What process in earth's interior causes subduction and sea floor spreading?

Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics


What is the difference between subduction and seafloor spreading?

Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate. Hope this helped :)


Would the most violent earth quacks be associated with spreading centers or subduction zones?

The most violent earthquakes are generally associated with subduction zones where tectonic plates collide and one is forced beneath the other. These subduction zones can produce very large and destructive earthquakes, such as the 2004 Indian Ocean earthquake and tsunami. Spreading centers, on the other hand, usually produce smaller earthquakes due to the gradual separation of tectonic plates.


What do you call the area where two tectonic plates meet?

The area where two tectonic plates meet is called a plate boundary. At plate boundaries, interactions between the plates can result in processes like subduction, seafloor spreading, or continental collision.


What is the difference between a transform fault and the subduction zone?

A transform fault is a boundary where two tectonic plates slide past each other horizontally. A subduction zone is where one tectonic plate is being forced beneath another. Subduction zones are associated with the occurrence of deep oceanic trenches and volcanic arcs, while transform faults are usually characterized by earthquakes.

What is the difference between a mid oceanic ridge and a subduction zone?

A subduction zone occurs at convergent plate margins where an oceanic plate is going underneath a continental plate or a less dense oceanic plate. A mid-ocean ridge is a divergent plate boundary on the ocean floor with a mountain range and a rift running through the center of it. Sea floor spreading also occurs at mid ocean ridges.


How does subduction is opposite of spreading boundaries?

In subduction zones, one tectonic plate is forced beneath another, causing the plates to converge. In contrast, at spreading boundaries, tectonic plates are moving apart from each other, which results in the formation of new crust as magma rises and solidifies. Thus, subduction zones involve plate convergence, while spreading boundaries involve plate divergence.


What is the difference between constructive and destructive plate margins?

a constructive (divergent) plate boundary, new crust is being created to infill the gaps caused by spreading plates. At a destructive (subduction-convergent) plate boundary, old, dense oceanic crust is diving into, and becoming part of the mantle.Read more: What_is_the_difference_between_a_constructive_plate_boundary_and_a_destructive_plate_boundary
