The Andes: A Comprehensive Overview

The Andes Mountains are more than just a geographical feature; they are a complex system that influences the climate, ecology, and culture of South America.

• Formation: The Andes were formed by the subduction of the Nazca Plate beneath the South American Plate. This process, which began millions of years ago, has resulted in the uplift of the mountains and the formation of volcanoes.
• Geology: The Andes are composed of a variety of rock types, including igneous, sedimentary, and metamorphic rocks. The mountains are also characterized by fault lines, folds, and other geological features.
• Climate: The Andes Mountains have a significant impact on the climate of South America. The mountains act as a barrier to air masses, creating distinct climate zones on either side of the range. The western slopes of the Andes are generally arid, while the eastern slopes are more humid.
• Hydrology: The Andes Mountains are the source of many of South America's major rivers, including the Amazon, the Orinoco, and the Paraná. The mountains also contain numerous lakes, glaciers, and wetlands.

Trends & Recent Developments
