Terrain refers to the physical features of a piece of land, including its shape, slope, and elevation. It can be flat, hilly, or mountainous, and it often influences how people use the land. For example, farmers may prefer flat terrain for growing crops, while hikers might enjoy exploring rugged, hilly areas. Different types of terrain can also affect weather patterns and ecosystems. In deserts, the terrain is usually dry and sandy, while in forests, it may be covered with trees and underbrush. Understanding terrain is important for activities like construction, farming, and outdoor recreation.
