Rocky hills are a type of landform that is characterized by steep slopes and sharp peaks. They are often composed of sedimentary rocks such as sandstone, limestone, and shale. The term 'rocky hills' can also refer to a range of mountains or hills with rocky terrain. Tors are large, free-standing rock formations that are found in areas of high elevation, such as rocky hills. Mesas are flat-topped hills or mountains with steep sides, which are also commonly found in rocky hill regions.
