Rolling hills are gentle, undulating landforms characterized by a series of low, rounded elevations. They are often found in various landscapes, including farmland, parks, and natural reserves. These hills can vary in size and shape, creating a visually appealing terrain that is often used for recreational activities like hiking and biking. The formation of rolling hills is typically the result of erosion and sediment deposition over time. They can be composed of different types of soil and vegetation, which support diverse ecosystems. Regions with rolling hills, such as the English countryside or the Appalachian Mountains, are known for their scenic beauty and agricultural productivity.
