Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.
This report describes how to build a model of the outer 300 km 180 miles of the earth that can be used to develop a better understanding of the principal features of plate tectonics including sea floor spreading the pattern of magnetic stripes frozen into the sea floor transform faulting thrust faulting subduction and volcanism.
For instance the atlantic ocean is believed to be expanding because of its few trenches.
