Why are divergent boundaries considered constructive while convergent boundaries are considered destructive?

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.

Divergent boundaries are considered constructive because they involve the pulling apart of tectonic plates, creating new crust from the mantle through volcanic activity. This process leads to the formation of new land and ocean basins. In contrast, convergent boundaries are considered destructive because they involve the collision of tectonic plates, leading to subduction zones, earthquakes, volcanic eruptions, and the destruction or recycling of crust.

convergent means coming together, i.e. subduction of crust into the mantle

Why are divergent boundary considered constructive while convergent boundaries considered destructive?
divergent - creates new crustal rockconvergent - destroys old crustal rock
Is subduction constructive or destructive?
It is neither, because plate is not being made or destroyed. Divergent is constructive. Convergent is destructive. Subduction is constructive.

What types of plate boundaries have subduction zone?
Convergent boundaries can form between two oceanic plates, between one oceanic plate and one continental plate, or between two continental plates.

Where are the 3 major kinds of boundaries?
Convergent boundaries (plates moving toward each other, also called destructive boundaries), divergent boundaries (plates moving away from each other (sometimes called constructive boundaries), fault lines (sideways movement).
What are types of plate boundaries?
The 3 general types are constructive, destructive, and conservative boundaries. Constructive (divergent) - plates move away from each other, typically creating a rift Destructive (convergent) - one plate will be subducted, or continental plates collide Conservative (transform) - plates grind past each other, stalling and slipping

What are the types of divergent boundaries?
The main types of divergent boundaries are mid-ocean ridges, where new oceanic crust is formed as tectonic plates move apart; continental rifts, where plates within continents separate, creating rift valleys; and back-arc basins, where oceanic plates are being subducted under continents, leading to extension and back-arc spreading.
