Why is Cloud and rain attracted to the rainforest?
Yes, as ty says, it's a cycle - and that is one important reason why it's vital not to cut down the rainforests. They are essential to maintaining a balanced atmosphere and enough rainfall. (The other forests are important too, but because of the heat, tropical rainforests are more 'active' in the evaporation/transpiration/rain cycle)
Actually it's a cycle... the rainforest I guess creates more rain, the rain helps the rainforest to grow...
It's the other way around, the rain forest grow where it rains a lot.
