When a player has legal control of the ball and the ball touches or travels over the imaginary vertical plane over the opposing team's goal line, he or she scores a touchdown. The ball can be touched by any part of the body with the exception of the hands (for throwing) and feet (for kicking). The type of score depends on where the ball is when it crosses the goal line. If the ball is in play and still in the field of action, it is a touchdown. If the ball is out of bounds anywhere on the field, it is a touchback. Otherwise, it is a safety. There are two ways to score a touchdown: a rushing touchdown and a passing touchdown. A rushing touchdown is scored when you run the ball into the end zone. You get a point for every yard you rush forward. A passing touchdown is also scored when the quarterback throws the ball into the end zone. You get six points for this type of touchdown. In order for a touchdown to be valid, the offensive team must advance the ball into the end zone (or try). If they do not, the opposition can file a foul return during their own subsequent possession.
