upper layers and only 1% on ground
• Vegetation: epiphytes (orchids) air plants
grow on branches. Lianas: woody vines

Deserts
• West coast of continents 20-30°latitude.
– Winds prevent moisture reaching area
– Baja, CA
• Rainshadows: Death Valley
– High mountain areas – lots of evaporation –
precipitation does not reach area
• Interiors of continents: Gobi Desert
– Distance from moisture is too great
