Geographical Hazards and Climate Zones. Peru physical geography presents a study in dramatic contrasts, where the pulse of the Pacific Ocean meets the thunder of ancient glaciers and the whisper of the Amazon rainforest.
Peru Mountains, Rainforest, and Coast: Geography of Three Ecosystems
It is the world’s highest navigable lake and a cradle of pre-Columbian civilization. Below the snow line, the valleys transition into the ceja de selva, or "eyebrow of the jungle," where the climate shifts dramatically.
This natural irrigation supports hardy vegetation and shapes the character of the coastal valleys, where Peru’s largest cities, including the capital Lima, are concentrated along the Pacific shoreline. Yet, this harsh environment is made bearable by the *garúa*, a unique coastal fog generated when the cold Humboldt Current chills the moist air above it.

The result is a compressed arrangement of ecosystems, running like distinct horizontal layers from the arid Pacific coast, through the world’s highest tropical mountain range, and into the vast, lowland basin to the east.
