Hello, I'm posting this for my 7 year old son, who asked me a question that I cannot answer, or find the answer to.
He wants an explanation for why the suns rays cannot escape once they enter our atmosphere, if they can get in in the first place they why can't they get out..??? We understand the greenhouse gases preventing the heat from escaping but why would they stop the heat from getting in in the first place. If someone can give us a clear answer I would appreciate it.
thanks for you time.
Mandy
