Ahh, actually, that is not true. The continents are moving. The processes by which they do this are pretty well established. We can even measure the rates at which they are moving. It is on the order of a few centimeters a year.

Agree. Continental drift is the movement of the Earth's continents relative to each other. The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s that a sufficient geological explanation of that movement was found.

I heard that every year a continent moves about 0.25-2 inches.

Yes, that is about right. However, I think that the upper limit is about 3 inches a year.
