Which hazard is not associated with wreck diving?

Wreck diving presents a variety of hazards, and among them, strong currents are typically not considered a direct issue related to the wreck itself. Instead, strong currents are more associated with specific dive locations based on tides and ocean conditions rather than the wreck structure.

The hazards directly linked to wreck diving include suction, which can occur in areas where debris or a sunken vessel creates a significant change in water flow. Sharp objects are common in wrecks due to rusted metal, broken glass, and other potentially dangerous materials that can cause cuts or injuries. Unstable structures present a risk as well, since wrecks may have weakened areas that could collapse or shift unexpectedly, posing a threat to divers exploring the site.

In contrast, while strong currents can affect many diving scenarios, they are not inherently tied to the structural dangers or specific physical conditions of a wreck. Thus, understanding the context of currents relative to wreck diving highlights why strong currents are not classified as a direct hazard of wreck exploration, making it the correct selection in this scenario.
