this is not the answer but the other one was stupid.
It is considered to be 'constructive,' because new crust is being formed and added to the ocean floor.
Sea floor spreading is considered a constructive process because it involves the formation of new oceanic crust at mid-ocean ridges. As tectonic plates move apart, magma rises to the surface and solidifies, creating new crust. This process helps in the continuous renewal of the oceanic lithosphere.
The spreading apart of plates is considered constructive because it results in the creation of new crust along divergent boundaries. As the plates move apart, magma from below the Earth's surface rises to fill the gap, solidifies, and forms new crust. This process leads to the growth of the Earth's surface and contributes to the renewal of oceanic basins.
Divergent plates.
A constructive plate margin or spreading centre known as the Mid-Atlantic-Ridge.
Ocean floor spreading is considered a constructive process. It occurs at mid-ocean ridges where tectonic plates diverge, leading to the formation of new oceanic crust as magma rises and solidifies. This process adds material to the ocean floor and contributes to the growth of ocean basins. In contrast, destructive processes, such as subduction, involve the recycling of crust back into the mantle.
Constructive plate margins are when two plates move away from each other, creating more ocean floor.
The Mid-Atlantic Ridge. Potentially the East African Rift system in the future
yes
They could help in creating new lithospheric (crust) plates. As in the case of divergent boundary, where new ocean floor is produced and expanded (sea-floor spreading).
constuctive
At 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.
