Which of the following describes common types of underwater navigation?

Natural navigation and compass navigation are fundamental techniques divers use for underwater navigation. Natural navigation involves using environmental cues such as topography, currents, and marine life to orient oneself and determine direction. Divers assess landmarks, the position of the sun, and the behavior of waves to navigate without devices.

Compass navigation, on the other hand, relies on the use of a compass, which provides a reliable means of determining direction underwater. Divers can set a heading and follow it, allowing for more precise navigation over longer distances or in featureless areas. By combining these two methods, divers enhance their ability to navigate safely and effectively while exploring underwater environments.

The other options present alternative forms of navigation but are not traditionally categorized as common types used by divers in typical underwater scenarios. For instance, GPS navigation relies on satellite signals, which are often not reliable underwater, and sonar navigation is specialized technology used primarily for mapping or exploring, not standard diving. Similarly, surface navigation focuses on navigating while at or near the surface of the water, and bubble navigation is not a recognized technique among divers. Visual and sound navigation can involve elements of natural navigation and environmental awareness, but they do not distinctly represent established methods like natural and compass navigation.
