The Amazon Rainforest in Brazil makes its own weather - a lot of that weather is rain! But what came first: the rain or the rainforest?
Why It Matters
- Average annual rainfall in a tropical rainforest is around 70 inches a year.
- Tropical rainforests are found in the equatorial regions where warm air rises, cools and precipitates.
- Transpiration in the rainforest leads to precipitation over the rainforest.
- Angiosperms move a lot of water from the soil to the atmosphere.
- Logging the rainforest has many deleterious effects. One is a change in the region’s climate.

- How do rainforests produce their own rain?
- What happens if the cycle of transpiration to precipitation slows down as happens in pine forests?
- Why are the tropical regions populated with angiosperms rather than gymnosperms?
- What do scientists fear the effect of continued logging will be on the rainforests?
