What are the fundamental differences between indoor and outdoor volleyball, and how do these differences affect gameplay?

Indoor and outdoor volleyball differ primarily in their playing environments and team sizes. Indoor volleyball is played on a hard court with six players per team, utilizing a net that is higher and closer to the ground. The game focuses on fast-paced, aggressive play with complex formations and strategies for blocking and attacking. Outdoor volleyball, particularly beach volleyball, is played on sand with two players per team, which requires more emphasis on individual skill and endurance. The softer surface and smaller team size lead to different strategies, such as more frequent dives and extended rallies.
