seafloor spreading
The theory of continental is not accepted as it is been disproved, but it was replaced by the theory plate tectonics. This theory accepted because of may factors including the discovery of mid-ocean ridges, subduction zones, and the tracking of plates via GPS and other means.
There are two types of zone theory they are concentric and subduction. The concentric zone theory states that urban land has to be classified as concentric zones.
The Theory of Continental Drift!
The continental drift theory was replaced by the theory of plate tectonics.
I think that continetal drift replaced his theory

The Theory of Plate Tectonics, Continental Drift states that there were previously Gondwana and Laurasia as named.The two continents eventually merged to the single mass, Pangaea, and then broke apart after coming together in subduction, to expand and "Drift"

Continental Drift Theory
Continental Drift.
...at constructive plate margins / boundaries.hence the term contructive, new crust is "contructed" here.(and destructed at a destructive plate margin / boundary / subduction zone.)
