A hillock is a small, rounded hill or mound that is typically lower than a hill. It can be formed through natural processes such as erosion or sediment deposition. Hillocks are often found in various landscapes, including fields, forests, and grasslands, and can serve as habitats for various plants and animals. These small elevations can also be significant in agriculture, as they may provide better drainage for crops. In some cases, hillocks can be used for recreational activities, such as hiking or birdwatching, making them valuable features in both natural and cultivated environments.
