What are the kinds of hills?

Hills can be classified into several types based on their formation and characteristics. Some common types include grassy hills, which are often covered in vegetation; rocky hills, characterized by exposed rocks and steep slopes; and conical hills, which have a pointed shape. Additionally, there are man-made hills, such as burial mounds or earthworks, and specific formations like drumlins, which are formed by glacial activity. Each type has unique ecological and geological features.
