Hills are raised areas of land that are smaller than mountains. They can be found all over the world and come in various shapes and sizes. Hills are often covered with grass, trees, and flowers, making them beautiful places to explore. People enjoy hiking on hills for exercise and to enjoy the view from the top. Many hills are formed by natural processes like erosion or the movement of the Earth's crust. Some famous hills, like Sugarloaf Mountain in Brazil or The Seven Hills of Rome, have historical significance and are popular tourist destinations. Hills can also provide habitats for wildlife, supporting diverse ecosystems.
