In general, tropical rainforests have hot and humid climates where it rains virtually everyday. The level of rainfall depends on the time of year. Temperatures vary through the year - but much less than the rainfall.
The Amazon rainforest has nearly 40,000 plant species, ranging from tiny mosses to huge trees.
