Rain is the lifeblood of all rainforests. It's the reason this lush, vibrant jungle can exist. Without it none of this exuberant plant life could grow and nothing else could live here either. But why does it rain in the rainforest? You might think it's just part of the weather system here... but it isn't. The forest itself makes rain as part of an ongoing water cycle.
Each tree can suck up hundreds of gallons of water every day, but will only use a small amount. The rest goes back into the atmosphere as water vapour released through tiny pores on the leaves.

Winds blow the vapour out across the canopy, collecting more and more moisture as they go. This saturated air is carried deep into the forest, where it falls again as rain. New trees suck up the rainwater and so the cycle continues... The forest acts as a kind of giant conveyor belt, a sort of huge Mexican wave of moisture travelling right across a continent.

Half of all rainwater that falls here in the Amazon is produced by the trees themselves. The scale of the system is simply staggering, this forest is so big it creates its own climate. Winds from the Atlantic ocean blow the water vapour westward, right across the Amazon basin, finally pushing it up against the mountainside.

A single droplet of water can take an incredible trip. It might be recycled through dozens of different trees and downpours, and travel more than 3,000 km before it reaches the mountains of the Andes. Eventually, rain falls and the whole water story begins again.
