Rainforests are more the product of the temperate climate and topography (steepness of terrain surrounding the rainforest area, such as steep hills or mountains) that receives a significant amount of rainfall than triggering the rainfall.
Rainforests do help contribute to overall global climate stability, because forests scrub carbon dioxide from the air (which is naturally dumped into the air through animals and people breathing, and of course in modern times by the internal combustion engines in our cars) and release free oxygen which animals (including humans) need. By removing the carbon from carbon dioxide, they counteract global warming (because carbon dioxide is a greenhouse gas, which means it causes the earth's atmosphere to retain more heat and causes global warming).

Rainforests contribute to rainfall through a process called transpiration, where trees release water vapor through their leaves. This water vapor evaporates into the atmosphere and eventually condenses to form clouds, leading to increased rainfall. The high levels of evapotranspiration from the dense vegetation in rainforests play a significant role in the water cycle and precipitation patterns.
Rainforests are dense, lush forests with high amounts of rainfall and diverse vegetation, while grasslands are open areas dominated by grasses and with less rainfall. Rainforests have high biodiversity and tall trees, while grasslands have shorter vegetation and support grazing animals. The two ecosystems have distinct plant and animal species adapted to their specific environmental conditions.
Tropical rainforests have high levels of sunlight and rainfall, making them one of the most productive and biodiverse ecosystems on Earth. This combination of sunlight and precipitation supports the lush vegetation and diverse wildlife found in these regions.
Grasslands typically have a drier climate with less rainfall compared to rainforests, which receive abundant rainfall throughout the year. Rainforests tend to have high humidity and consistent temperatures, while grasslands can experience more extreme temperature fluctuations between day and night. Additionally, rainforests have a more stable climate with less seasonal variability compared to grasslands.
Hawaii is a state that receives a lot of rainfall but does not typically experience snowfall due to its warm tropical climate. The state's lush rainforests and frequent showers contribute to its reputation for being one of the wettest states in the U.S.
Rain forests are located along the equator due to the temperatures being warm all year round. The equator also has the most amount of rainfall.
