What is a consequence of greater reef height at the forereef?

The consequence of greater reef height at the forereef is greater protection from waves. Taller reefs act as natural barriers, which can absorb the energy of incoming waves. This protective mechanism helps to reduce the impact of wave action on coastal environments and marine ecosystems situated behind the reef. As waves break against the reef, it dissipates their energy, creating calmer waters in the lagoon or shoreline area, which can significantly benefit both marine life and human activities nearby.

In scenarios where the reef is taller and healthier, such as with a more complex structure that includes various nooks and crannies, fish and other marine organisms find refuge and breeding grounds, which can also support longer-term ecological health. Additionally, this wave protection is vital in maintaining the stability of shorelines, preventing erosion, and promoting the overall resilience of coastal ecosystems.

While the other choices may also relate to reef characteristics, they do not directly link to the height of the reef as clearly as wave protection does. Increased recreational opportunities, more visibility for divers, and higher biodiversity may result from a healthy reef ecosystem, but they do not necessarily correlate directly with reef height in the specific context of wave protection.
