Roasting tends to be a very long and low heat cooking done over 6-8 hours usually with thick meat cuts like turkeys or hams or chicken in a covered pan. This makes the meat juicy and tender. Baking is just putting something on a flat sheet pan and exposing it to the ovens heat directly for 20-30 minutes to quickly heat it up and crisp it.
