Question

Give geographical reasons-

The rain forests of Brazil are known as ‘lungs of the world’.

Answer 1

1. Located near the equator, Brazil’s Amazon rainforests have dense, year‑round green vegetation, high rainfall, and abundant sunlight, so trees carry out intense photosynthesis and release large amounts of oxygen.
2. The vast forest area absorbs large quantities of carbon dioxide and stores carbon, helping to purify the air and regulate the global atmosphere; hence, they are called the “lungs of the world.”
