The river known as the "Mother of All Rivers" is the Amazon River. Spanning across multiple countries in South America, including Brazil, Peru, and Colombia, the Amazon is the largest river in the world by discharge volume and is considered one of the longest rivers, surpassing even the Nile in certain measurements. The river and its surrounding rainforest are vital ecosystems, home to an incredible diversity of flora and fauna. The Amazon's expansive watershed plays a crucial role in global climate regulation and is often regarded as a lifeline for the many communities that depend on its resources.
