A large hill is a natural elevation of the Earth's surface, typically rising significantly above the surrounding terrain. It is smaller than a mountain but can still provide a notable change in landscape. Large hills can be formed through various geological processes, including erosion, sediment deposition, and volcanic activity. These hills often serve as important habitats for various plants and animals. They can also be popular recreational areas for activities such as hiking and picnicking. Many large hills, like those found in the Appalachian Mountains or Rocky Mountains, offer scenic views and unique ecosystems.
