A constructive margin is when a oceanic crust subducts a contiental crust. (when an oceanic plate is forced under a continental plate it is called subduction.)
VOLCANOS are found along the zones of subduction, and I have also heard that vey violent earthquakes can occur, however I am unsure whether this is true and I believe on volcanos occur.
41 MAYFIELD CLOSE!! thats where i live!! hehe anyway they are when the tectonic plates move and push upwards together relesing magma xx
hope that helped!! my name is sara citozi btw!! xx
Constructive Boundaries, are zones of interaction between plates, involving their movements away from each other, thereby creating an opportunity for new plate/crust to emerge/be formed.
Two oceanic plates move away from each other. the magma oozes out, and a ridge is formed gradually as lava collects.
at a constructive plate margin two plates move away from each other, magma rises and solidifies in the gap creating a new area of crust. e.g The island of Surtsey.
Because thats where the new oceanic lithosphere is produced.

The Divergent Boundaries.
A destructive plate boundary :)
Destructive
Mount Pinatubo is on a destructive plate boundary; it is above a subduction zone
A tsunami usually occurs on a destructive plate boundary.
No, Iceland is on a constructive plate boundary.

mt Popocatépetl is a divergent plate boundary also known as a constructive boundary or an extensional boundary
A constructive plate boundary, as it pushes land upwards (which formed the mountains)

The type of boundary that the Andes mountains are, in South America, is a convergent plate boundary. This was formed from the collision of the South American plate boundary and the Nazca plate.
A constructive/divergent plate boundary
A constructive boundary is where to plate boundaries separate apart just like when the north American plate (San Andreas fault USA )
