The landforms in the interior of the continents and at their margins mostly differ because of the difference in geological activity.
Explanation:
The landforms that are found in the interior of the continents tend to be old. They also are mostly consisted of sedimentary and metamorphic rocks. In general the erosion is much more evident and dominant, thus the landforms also are with lower elevations when compared with the ones on the edges. This is due to the lack of geological activity as the interiors of the continents tend to be far away from the plate boundaries.
The landforms on the edges of the continents tend to be younger in general. The reason for that are the subduction zones and intense geological activity. The intense geological activity is due to the close proximity of the plate boundaries. The landforms tend to be higher in general, and volcanic arcs are also a common sight.

The correct answer is - Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement.
Harry Hess is one of the people that is most important when it comes to the proving and world wide acceptance of the continental drift theory.
Hess was very interested in the topic, and he was constantly looking for clues that would bring light to it and finally have a definite proof of it. While sailing through the Atlantic and doing some examinations, Hess noticed that there high mountains in the water, having flat peaks, and being arranged in an interesting manner. These underwater mountains, named guyouts, were the highest at a certain point, and than on both sides, as the distance was increasing they were becoming smaller and smaller.
What Hess stumbled upon was the seafloor spreading and how it works, and he recognized that quickly. He immediately went on to share what he discovered, that there's magma coming from bellow, solidifying and spreading, thus creating new crust while pushing the old crust away from the center, which is the reason why the continents are moving.
