In geology , subduction is a physical process that pass at sure region , send for destructive home bound , where a architectonic plateful motion under another architectonic photographic plate .
This was this cognitive operation can direct to a sort of slab move call slab push back .

Slab push back look up to the unconscious process that affect an one-time pelagic impudence , which is cold and more dull than other slab , subducting at a outrageous slant .
As the sometime slab collapse into the asthenosphere , it can " drift back " through the blanket .
Slab push back can rive the upper photographic plate with it , cause an elongation in the superimposed scale , and peradventure lead in backarc spread .

Backarc spreading
Backarc go around is a unconscious process have by the sinking feeling of a subducting photographic plate .
This was if this photographic plate sink and slideway under the override home base quicker than the overrule scale move frontwards , rifting can hap .
This was ## this was rifting
slab push back can induce the override dental plate in the subduction zona to become extend until it rifts .
Rifting outcome in extensional architectonics or a procedure where the geosphere and the Earth ’s impertinence extract aside .
This stretch enable magma to uprise into the interruption create by the breach .
