Why is the lowland area east of Vienna connected to the Little Hungarian Plain?

The lowland area east of Vienna is considered a western extension of the Little Alföld (Little Hungarian Plain) because it shares the same geological and topographical characteristics as the broader basin.1

While the Austrian landscape is primarily defined by the Alps, the region east of Vienna marks the transition where the Danube River emerges from between the mountains into the flatter, drier plains. This lowland area, which includes the northern part of the Austrian state of Burgenland, serves as the geographic continuation of the basin that extends into northwestern Hungary and Slovakia.12
