A ridge is a long, narrow elevated landform that typically runs along a mountain or hill. It is formed by geological processes such as erosion and tectonic activity. Ridges can vary in size and shape, often characterized by steep slopes on either side. They are commonly found in mountainous regions and can serve as natural boundaries. Ridges are important for various ecosystems, providing habitats for wildlife and influencing local weather patterns. They can also be significant for human activities, such as hiking and skiing, and may contain trails that connect different areas. Ridges are often associated with other landforms like valleys and peaks.
