What is a sky ball serve in volleyball?
A Sky ball serve is usually a underhand serve on a beach court where the ball travels a long way up and comes down in a straight line. This made it hard for the opposing team to receive or pass the ball to their team mates. Factors: 1. The ball gains momentum when coming down making it more painful for the other team to receive the ball 2. When the ball is coming down the sun may get in the way therefore momentarily blinding the player. 3. The Wind may change the path of where the ball might hit making it harder for the opposition to receive the serve. The Sky ball origin was a tactic originally used by the Brazilian Volleyball Team.

Types of serves in volley ball?
Gotten from http://wiki.answers.com/Q/Special:UnAnsweredQ&tid=2982 * Underhand and Overhand Serve: refers to whether the player strikes the ball from below, at waist level, or first tosses the ball in the air and then hits it above shoulder level. Underhand serve is considered very easy to receive and is rarely employed in high-level competitions. * Sky Ball Serve: a specific type of underhand serve occasionally used in beach volleyball, where the ball is hit so high it comes down almost in a straight line. This serve was invented and employed almost exclusively by the Brazilian team in the early 1980s and is now considered outdated. In Brazil, this serve is called Jornada nas Estrelas (Star Trek). * Line and Cross-Court Serve: refers to whether the ball flies in a straight trajectory parallel to the side lines, or crosses through the court in an angle. * Top Spin: an overhand serve where the ball gains topspin through wrist snapping. This spin causes the ball to drop faster than it appears to a passer receiving it. * Floater: an overhand serve where the ball is hit with no spin so that its path becomes unpredictable. This type of serve can be administered while jumping or standing. This is akin to a knuckleball in baseball. * Jump Serve: an overhand serve where the ball is first tossed high in the air, then the player makes a timed approach and jumps to make contact with the ball. There is usually much topspin imparted on the ball. This is the most popular serve amongst college and professional teams.* Jump Float: This is a serve like the jump serve and the floater. The ball is tossed lower than a topspin jump serve, but contact is still made while in the air. This serve is becoming more popular amongst college and professional players because it has a certain unpredictability in its flight pattern. * Round-House Serve: the player stands with one shoulder facing the net, tosses the ball high and hits it with a fast circular movement of the arm. The ball is hit with the palm of the hand, creating a lot of topspin. * Hybrid Serve: An overhand serve delivered similarly to a top spin serve; however, it has more pace than a floater, but has a similar unpredictable path.
