Terrains refer to the physical features of a land area, including its shape, elevation, and natural characteristics. They can vary widely, encompassing mountains, valleys, plains, and plateaus. Each type of terrain influences the climate, vegetation, and wildlife found in that region, making it an essential aspect of geography. Different terrains can also affect human activities, such as agriculture, transportation, and urban development. For example, mountains may limit access and create challenges for building infrastructure, while plains often provide fertile land for farming. Understanding terrains helps in planning and managing land use effectively.
