Mountain streams are small, fast-flowing bodies of water that originate in mountainous regions. They are typically fed by melting snow or rainfall and flow down the slopes, carving out valleys and creating unique ecosystems. The water in these streams is often clear and cold, providing a habitat for various aquatic life, including fish and insects. These streams play a crucial role in the environment by contributing to the water cycle and supporting local wildlife. They can also be important for human activities, such as fishing, hiking, and recreation. Additionally, mountain streams help to shape the landscape, creating beautiful scenery in national parks and nature reserves.
