What are hills?

Hills are natural elevations of the Earth’s surface that are smaller and lower than mountains. They often have rounded tops and are less steep compared to mountains. Hills are formed by processes such as erosion, deposition, or the uplifting of Earth’s crust over time. They can support various types of vegetation and are often used for agriculture, grazing, and human settlements. Hills also influence the local climate and water flow in their regions. They add to the diversity of landforms and are an important part of the Earth’s geography.
