I was told that birds glide on the thermals. Well, that was confusing. What it means is that when there is hot air rising in the sky, the birds glide on it. They don’t flap their wings and they look like they are have a good time.
I’m starting with three pictures I drew that show the basic idea of hot air rising.
If you look up in the sky and see birds floating around, they are gliding on the thermals.
