DO you know that world’s largest river is in the sky! What? Just read this article and you will find your answer. And also how trees help in to produce rainwater. In the end, you will get the answer to more questions than you had expected.

The Amazon rain forest covers 40% of South America. It contains nearly 400 billion trees and creates 1/5th of our planet’s oxygen. The river basin feeding the mighty Amazon carries one-fifth of earth river water into the Atlantic Ocean every day.

This water adds enough mass to the continent that it distorts the gravitational field over. But the river in the center of this is not the biggest river on Earth. The biggest one is flying in the Sky.

One can get a clear view of the Amazon basin in Google earth app, but we can’t see it clearly, if we are in space, as it is always obscured by clouds. These clouds contain probably 400 billion gallons of water or more.

How do trees help in the rain?

I think you have got some idea from this pic. When pores on leaves open up during photosynthesis plants also lose a lot of water. This evaporation pulls water from the roots. This is the same as when we suck some liquid by straw.

A single Palash tree in the Amazon can release 1000 litres of water into the atmosphere every day. Altogether trees in the Amazon basin released approx 20 billion tons of water or 20 trillion litres, each day enough to fill 8 million Olympic swimming pools. Boiling that amount of water would require the energy from more than 30,000 hydroelectric power plants, like China’s “Three Gorges Dam” the largest in the world.

But trees do it all with the power of the sun. The living water pump creates a river in the sky about the Amazon is tracing from the ocean to the Andes, that moves even more water than the Amazon River itself and the rain. This sky river creates the reason, the world’s largest rainforest even exists.

But it takes more than water in the air to make rain. Even the driest place on earth, a cubic metre of air contains billions of water molecules, but H2O itself cannot form droplets on its own ever. Much like the planets they nourish, raindrops grow from seeds. At the heart of every raindrop is a tiny impurity, anything from specs of dust, to salt, pollen, or even chemicals.

Rain seeds give water molecules something to cling to, so they can grow into droplets. Trillion of this droplets make up every cloud we see and when they eventually get big enough and heavy enough they fall. So that’s rain.

Why do someplace gets so much rain and others don’t?

Because not every place on earth has the same type or the same number of rain seeds in the atmosphere. And that’s the main reason why we need forest for rain. 95% of the Amazon’s rain seeds are made by the trees and plants that live there.

Along with water vapour trees in the Amazon release chemicals that act as super sticky H2O magnets. These biogenic volatile organic compounds are how the forest makes its own rain. The year of the Amazon contains just 300 particles per cubic CM making it the cleanest air on earth.

A very interesting fact that whenever trees needed in there in a different amount of rain attracting chemicals seeding more of their own clouds and rain. And the water released by the trees condenses into clouds at lowest nearby air pressure. This creates the wind that drives this river in the sky from the Atlantic all the way to the Andes.

In our school is we had thought that water evaporates from ocean most to the land falls in the form of rain and again the process repeats but we never know about this fact that trees generate rain and Mix-cloud for its own.

Trees around the globe act like in great green palms responsible for 90% of the water in the atmosphere.
