How are rounded hills formed?

Rounded hills are typically formed through a combination of erosion and weathering processes. Over time, wind, water, and ice wear down the sharper edges of mountains and rock formations, resulting in the smoother, rounded shapes we see today. Additionally, geological processes such as sedimentation and volcanic activity can contribute to the formation of rounded hills. These processes work together over long periods, creating the gentle slopes and rounded contours characteristic of such hills.
