Hilly areas are regions characterized by elevated terrain, often featuring slopes and valleys. These landscapes can vary in height and steepness, providing unique ecosystems and habitats. Hilly areas are commonly found in mountain ranges, such as the Himalayas or the Appalachians, and can influence local weather patterns and biodiversity. The geography of hilly areas affects human activities, including agriculture, transportation, and settlement patterns. Farming in these regions often requires terracing to manage the slopes, while roads may need to be carefully constructed to navigate the terrain. Hilly areas can also offer recreational opportunities, such as hiking and skiing, attracting tourists and outdoor enthusiasts.
