magma (molten rock) under the crust is going in circles ~ it gets hot rises up then cools down and goes back down again and because it goes in circles its pulling the plates apart and that's whats making then drift slowly apart.
Unequal heat distribution.
Despite what Creationist would have you believe (when debating other topics) theory does not mean hypothesis or speculation. In science, a theory is an explanation of the natural world that is well-substantiated by evidence. This includes a number of explanations that are so well-substantiated by evidence that there is virtually no doubt among scientists that it is the correct explanation. These include the theory of plate tectonics, the thoery of evolution, atomic theory, and germ theory.
Einstein died before plate tectonics became an accepted geological idea.
One of the ideas that was used to dispute the theory of plate tectonics was the concept of "fixism" or "fixist theory." Fixism proposed that the positions of continents and landforms on Earth were permanent and unchanging. According to fixism, the continents were believed to be stationary, and there was no mechanism for their movement or shifting. Fixism was prevalent in the early 20th century and before, with many geologists and scientists rejecting the idea of continental drift, which eventually led to the development of plate tectonics theory. However, as more evidence accumulated, particularly in the mid-20th century, supporting the movement of continents and the presence of large-scale tectonic plates, the theory of fixism was gradually abandoned in favor of the more widely accepted theory of plate tectonics.
There are no commonly accepted opposing scientific views on plate tectonics or the existence of the supercontinent Pangaea.
Tectonic Plates Theory, which is now accepted as fact.

the convection currents in the mantle under the earths curst is moving the broken plates in earths lithosphere causing the plates slide across the lithosphere. this process is called tectonics. (jon lay wrote this,)

it wasnt accepted. Wegener's theory of continetal drift wasnt accepted. the theory of plate tectonics was created when scientists discovered about sea floor spreading and magnetic reversals. but i dont know when the theory of plate tectonics was created. so you can ask about that.
Tectonics is the large scale processes effecting the crust. The large scale process that is accepted to be occurring is plate tectonics (crust separated into plates that move and interact). The theory of continental drift suggested that continents moved however it never proposed a mechanism, plate tectonics is that mechanism that explains what alfred wegener saw. So back to your question similarities between what i think you mean modern tectonics i.e. plate tectonics and continental drift is that they both suggest the crust is moving.
Are you referring to plate tectonics whichI believe is more than a theory. At one time all the continents were together in a land mass called Pangea. Sea floor spreading caused them to separate forming the present continents which generally look like a jig-saw puzzle you can put together. It was Alfred Wagner, a German, who first pointed this out in 1911 though the reason s were not known at the time.

A theory is a widely accepted explanation based on experimental results.
At times, all the world's continents have been glaciated. A feature called 'inselberg' is often accepted as evidence of ancient glaciation unless some other explanation is more credible.
I do, looking at the map it does look like a puzzle and all the continents look like they connect or used to connect.
