Amazon Rainforest!

The Amazon Basin produces its own rain! The air here is cleaner than most everywhere on Earth.

It allows scientists to experiment and investigate clouds and condensation. During the wet season the clouds consist or organic material. Then these particles are released into the rainforest.

My opinion: This is good because scientists can predict the precipitation in clouds. They also can test the air particles since the air is good here. I did not know that the air is cleanest in the rainforest. Scientists should keep studying clouds to predict the air and weather in other places of the world.
