The term "mountainous" refers to areas characterized by significant elevation changes, typically featuring steep slopes and rugged terrain. These regions often contain a series of mountains, which are large landforms that rise prominently above their surroundings. Mountainous landscapes can be found on every continent and are often home to diverse ecosystems. Mountainous regions can influence climate and weather patterns, as they can block winds and create rain shadows. They are also popular for outdoor activities such as hiking, skiing, and rock climbing. Many mountainous areas are protected as national parks or reserves to preserve their natural beauty and biodiversity.
