Scuba diving is an underwater activity where a person uses a special breathing device, called a scuba tank, to explore beneath the water's surface for extended periods. Divers wear equipment like a mask, fins, and a wetsuit to help them see, move, and stay comfortable underwater. The activity can be recreational, such as exploring coral reefs or shipwrecks, or professional, such as underwater research or rescue. Scuba diving requires training to ensure safety and includes learning how to use the equipment and handle underwater conditions like pressure changes.
