How does wind come from the tree ?

My daughter asked me this question, this morning, with complete sincerity and innocence. I hope she keeps asking me questions like this, I hope I don't stop her in anyway from expressing her curiosity. I tried to be as thoughtful as possible and tried to explain that wind blows around and does not come from tree. She then followed it up with another question - Why do clouds move ?

Last week she looked into my eye and asked me how can she move that black thing in my eye as I do. I asked her to look in the mirror and then asked her to see all around without moving her neck. She was thrilled to know that she could also move the black thing too.
