What is a condition that may not lead to CZ development?

The correct answer highlights insufficient water depth as a condition that may not lead to Coastal Zone (CZ) development. Coastal zones are typically characterized by their proximity to shorelines where land meets the ocean, and adequate water depth is critical for the creation of various marine habitats and ecosystems. Insufficient water depth can hinder the establishment of environments necessary for the development of coastal zones, as it may limit areas for marine life to thrive and restrict the types of coral reefs or other structures that can exist in those areas.

On the other hand, high water temperature, increased salinity, and low silt concentration can all play varying roles in affecting the development and health of coastal zones. High water temperatures can potentially lead to reef bleaching and changes in species composition, increased salinity may influence the types of plants and animals that can inhabit these areas, and low silt concentration can affect sediment deposition which is vital for certain ecosystems. However, none of these factors directly inhibit the formation of coastal zones in the same way that insufficient water depth does.
