A ravine is a deep, narrow valley formed by the erosion of land, often by water flow. These natural features can be found in various landscapes and are typically characterized by steep sides and a stream or river running through them. Ravines can vary in size and depth, and they often serve as important habitats for wildlife. Ravines are commonly associated with forests, mountains, and river systems. They can provide unique ecosystems, supporting diverse plant and animal species. Additionally, ravines can play a role in drainage and water management, helping to channel excess rainwater away from surrounding areas.
