🔍 Key Concepts

• Tidal patterns: semidiurnal, diurnal, and mixed tides and what each pattern looks like over a 24‑hour period • The idea that some tide tables show one high tide slightly higher than the other—this specific difference has a special name • Solar vs lunar effects on tides and which terms describe patterns vs causes

💭 Think About

• Focus on which option names a type of daily tide pattern and which might instead describe a small difference between successive highs or lows • Ask yourself: does the question describe how many tides occur per day, or the difference in their heights? Match that to the correct term. • Think about which answer choices are commonly seen as the main three global tidal regimes, and whether any of those is actually a word used for the small inequality between two highs or two lows.

✅ Before You Answer

• Identify which terms in the choices describe patterns over a tidal day (number and size of highs and lows) rather than a specific difference between two tides • Verify which terms are associated with lunar-solar causes versus descriptive labels for the shape of the tide curve • Before choosing, ask: does this term directly refer to the inequality in height of successive highs or lows, or to the overall pattern of the tides?
