The landform region predominating in the area north of the Alpine chain is the European Plain.

Here's why:

* The European Plain: This vast, flat region stretches from the northern foothills of the Alps all the way to the Arctic Ocean. It encompasses countries like Germany, Poland, Ukraine, and Russia.

* Alpine Chain: The Alps form a significant mountain range that runs through central Europe. They create a natural boundary between the European Plain and the Mediterranean Sea.
