Good Day....

Wegener observed that appalachian mountains in eastern north america match mountains in Caledonian Mountains (Scotland).

It is because according to continental drift theory, the continent were once connected before forming a single landmass known as pangea. Convection current in the mantle causes the lithosphere to move in a certain direction. Movement of the lithosphere like seafloor spreading will result to drifting of the continents.

Hope it helps...=)
