A yama, or mountain, is a large landform that rises prominently above its surroundings, typically characterized by steep slopes and significant elevation. Mountains are formed through geological processes such as tectonic plate movements, volcanic activity, and erosion. They can be found on every continent and often serve as natural barriers, influencing climate and ecosystems. Mountains are home to diverse flora and fauna, adapted to varying altitudes and climates. They play a crucial role in the water cycle, acting as sources for rivers and lakes. Famous mountain ranges include the Himalayas, Andes, and Rocky Mountains, each with unique geological features and cultural significance.
