🔍 Key Concepts

• Tidal patterns and terminology – know what each option means (apogean, perigean, bore, double high water) • High water stand and slight fall – focus on the description of a small dip or pause during high water creating an extended high-water period • Local tidal anomalies seen in places like the English Channel or certain European ports

💭 Think About

• Which of these terms describes the shape of the tide curve at a single location (how the height changes over a few hours), rather than the overall strength of the tide over the whole month? • Which options are linked to the Moon’s distance from Earth, and which are about unusual behavior during a single tidal cycle? • Think about where you might see a tidal bore versus where you might observe an extended stand at high water with a small dip in the middle.

✅ Before You Answer

• Match the definition: the question describes a slight fall during high water, causing a longer stand at high water – which term is defined that way in your seamanship or tidal reference? • Verify which terms (apogean and perigean) relate to the Moon being farthest or closest to Earth and how that affects spring/neap tide ranges rather than the detailed shape of one high water. • Confirm what a bore is (a steep-fronted wave moving upriver) and whether that matches the slow, slight fall in the middle of high water described here.
