Final answer:
The Interior Lowlands and the Northern Lowlands are flat regions suitable for agriculture and shaped by geological processes.
Step-by-step explanation:
The Interior Lowlands is a flat region covering nearly two million square miles and encircling the Hudson Bay. It is rocky in the northern part and is characterized by plains. The Interior Lowlands have been shaped by glaciers and rivers, similar to the Great Plains. It is an important agricultural region with good soils.
In Europe, the Northern Lowlands extend across northern Europe from southern France to the Ural Mountains of Russia. Similar to the Interior Lowlands in North America, the Northern Lowlands possess excellent farmland and are known as the breadbasket of northern Europe. The land is flat to rolling with fertile soils.
Overall, the Interior Lowlands and the Northern Lowlands are flat regions that are suitable for agriculture and have been shaped by geological processes.
