no magma riseing thur gaps in plate causes them to move called seafloor spread
by plate tectonics
Plate tectonics
Subduction is part of the geological process of plate tectonics. A subduction zone is a place where the oceanic plate is sinking back in to the mantle (usually at the edge of a continental plate.
plate tectonics is a theory because t explains the formation, movement, and subduction of earth' s plates.
Subduction
There are 2 tectonics theories namely: divergent boundary and subduction zone. The boundary of the plate tectonics where two plates are placed is called divergent boundary while the subduction zone is a convergent boundary where in one plate is subducted on another.
The volcanism at Lassen National Park is caused by convergent plate tectonics, specifically the subduction of the Gorda Plate under the North American Plate.
Aleutian Islands were formed from the subduction of the plate tectonics.
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
If you are talking about plate tectonics, the action you're referring to is called subduction.
some features caused by plate tectonics would be folded and faulted mountain chains. subduction zones are also some important features caused by plate tectonics. the oceanic crust goes underneath the continental crust creating a subduction zone at the plate boundaries.parvaiz mansoori
