Backshore zones are typically exposed to waves under which conditions?

• A. During calm, offshore winds.
• B. Only during neap tides.
• C. During storm conditions.
• D. Only at night.

Answer: (C)

Backshore zones sit above the normal reach of waves and are typically dry. They’re only reached when waves have enough energy to run up well inland. Storm conditions generate large, powerful waves and often a storm surge, raising water levels and driving a strong swash that can reach the backshore. In calm conditions, waves are small and don’t reach that far; neap tides reduce tidal range but don’t provide the high-energy run-up needed; nighttime doesn't inherently change wave energy either. So storms are the conditions under which backshore zones are exposed to waves.
