Answer:A) The continents move.
B) The continents drifted apart over a long period.
C) The continents were once connected as one landmass.
Explanation:
Continental drift is the theory that continents were once ONE huge landmass and each continent shifted relative to other continents over many years. In 1912, Alfred Wegener named the single landmass Pangea.
According to Wegener, Pangea split about 200 million years ago, giving way to the oceans currently separating the continents. Prior to 1912, some scientists such as Roberto Mantovani had attribute the separation of the continents to volcanic activity, but this has since been proven to be wrong.

As countries become more developed, the productivity edge that urban regions have over their countries declines. This makes sense, development leads to urbanization which leads, eventually, to the convergence of the productivity of metro areas and the country as a whole. Cities are changing fast.
