• Climate Barrier: Blocks Pacific moisture; western slopes wet (rain/snow), eastern slopes dry (rain shadow).

Economic Effects

• Mining: Andes host vast copper, gold, silver, lithium deposits – Chile's economic backbone.
• Agriculture: Andes provide irrigation water (snowmelt) and shelter from southern winds for central valley farming.
• Tourism: Hiking, skiing, mountaineering attract global visitors.

Social & Cultural Effects

• Mapuche Heritage: Indigenous people of the Andes maintain centuries-old traditions.
• National Identity: Mountains are a symbol of Chilean pride and sovereignty.
