What is a major benefit of using moorings over traditional anchoring?

Using moorings over traditional anchoring offers a significant advantage in reducing environmental impact, which is why this option stands out as the correct response. Moorings are designed to minimize damage to the seabed and surrounding marine life. Traditional anchoring can disturb sensitive ecosystems, particularly in areas with delicate coral reefs or seagrass beds. The dragging or placement of anchors can uproot or destroy these vital habitats.

In contrast, moorings are typically fixed in position and allow vessels to tie up without touching the seabed directly. This stationary nature helps protect the environment from the harmful effects of anchors, thereby supporting overall marine health. The use of moorings can help maintain biodiversity and preserve the integrity of marine habitats, which is crucial in underwater ecosystems.

While other options present their own merits—such as ease of use and cost—these attributes do not have the same substantial positive impact on the environment as the use of moorings does.
