"Alpine" refers to the high mountain regions, typically above the tree line, where the climate is cooler and the environment is characterized by rugged terrain, rocky landscapes, and unique vegetation. These areas are often found in mountain ranges such as the Alps, Rockies, and Himalayas. The term can also describe the specific flora and fauna that thrive in these conditions, including hardy plants and animals adapted to the harsh climate. In addition to its geographical meaning, "alpine" is used in various contexts, such as alpine skiing, a popular winter sport that takes place on snow-covered slopes. The term can also refer to alpine ecosystems, which are important for biodiversity and often serve as indicators of climate change due to their sensitivity to environmental shifts.
