Why are rainforests only grown in some parts of the world?

Rainforests are typically found near the equator where there is consistent sunlight and warm temperatures year-round. They also require high levels of rainfall, usually around 80-400 inches per year, which is why they are mostly located in tropical regions. Additionally, the soil in rainforest areas tends to be nutrient-rich due to the rapid decomposition of organic matter, which supports the diverse plant and animal life found in these ecosystems.
