Mountain structures are large landforms that rise prominently above their surroundings, typically characterized by steep slopes and a peak. They are formed through geological processes such as tectonic plate movements, volcanic activity, and erosion. Common types of mountain structures include fold mountains, fault-block mountains, and volcanic mountains. These formations can vary greatly in size and shape, influencing local climates and ecosystems. Mountain structures often serve as natural barriers, affecting weather patterns and creating distinct habitats. They are also important for human activities, providing resources like minerals and opportunities for recreation, such as hiking and skiing.
