22 Facts About Amazon rainforest

Amazon rainforest, Amazon jungle or Amazonia is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America.

Name Amazon rainforest is said to arise from a war Francisco de Orellana fought with the Tapuyas and other tribes.

The Amazon rainforest has been in existence for at least 55 million years, and most of the region remained free of savanna-type biomes at least until the current ice age when the climate was drier and savanna more widespread.

However, the Amazon rainforest still managed to thrive during these glacial periods, allowing for the survival and evolution of a broad diversity of species.

In present day, the Amazon rainforest receives approximately 9 feet of rainfall annually.

The result indicates that the Amazon rainforest could be threatened through the 21st century by climate change in addition to deforestation.
