Valleys are low-lying areas of land situated between hills or mountains, often formed by the erosion of rock and soil over time. They can be created by various geological processes, including glacial activity and river erosion. Valleys can vary in shape and size, with some being wide and flat, while others are narrow and steep-sided. These natural formations are not only significant for their beauty but also play a crucial role in ecosystems. Valleys often host rivers and streams, providing essential water sources for wildlife and human settlements. They can also be fertile areas for agriculture, making them vital for food production in many regions.
