Conduction is the transfer of heat from one molecule to another through a substance. Not all substances conduct heat at the same speed. Metals are considered good conductors since they can speedily transfer heat.

Heat is transferred by a moving fluid in contact with a solid, e.g. a breeze on a summer day. It's actually a little more complicated than this, because conduction plays a large role still.
