Why does deflecting the elevators down create an upward lift?

If you deflect the elevator, an aileron, or the flaps downward, each surface always creates a lift force in an upward direction. The reason for this behavior is that the air has to follow a longer path over the top, which creates a lower pressure that results in a lift.
