What is Scuba Diving?

Scuba diving is a water sport activity that takes place underwater. Participants breathe compressed air via a regulator assembly that is attached to a metal cylinder (usually strapped to the diver's back).

Most of the people who enjoy scuba diving are recreational divers (e.g. for fun). They will explore different kinds of underwater environments (e.g. coral reefs, kelp forests, freshwater lakes, quarries, and rivers).

Nonetheless, some people actually scuba dive for work. Typical examples include marine biologists, public safety divers, and underwater welders.
