Which outcome occurs when coral reef zonation patterns shift toward deeper waters?

💡 Explanation

Deeper waters mean reduced light penetration, and therefore the light compensation point for coral symbiosis shifts downward; because coral zonation is strongly limited by light, this results in reefs growing at lower depths, rather than nutrient changes or coastal effects.

• If a volcano erupts effusively, releasing basaltic lava onto a gentle slope, which consequence follows?
• A river delta extends into a shallow sea; which outcome occurs when sediment supply decreases while wave energy and longshore drift remain constant?
• A massive influx of freshwater from melting glaciers into the North Atlantic alters seawater density; which consequence follows?
• A granite outcrop experiences increased rainfall. Which outcome follows regarding feldspar minerals within the outcrop?
• What happens to stream discharge when increased impermeable surfaces cover a watershed?
• Which outcome occurs when excessive rainfall impacts agricultural topsoil?
