Difficulty: Easy
Correct Answer: None of the above
Explanation:
Introduction / Context:
Two classic terms describe extremes in tidal range: spring tides (maximum range) and neap tides (minimum range). Knowing which corresponds to the smaller rise and fall is fundamental for navigation and coastal planning.
Given Data / Assumptions:
Concept / Approach:
Spring tides occur when Sun, Earth, and Moon are aligned (new/full moon), reinforcing gravitational effects. Neap tides occur when the Sun and Moon are at right angles (first/third quarter), partially canceling tide-generating forces and yielding the minimum range.
Step-by-Step Solution:
Identify the target phrase “minimum rise/range.”Recall correct term → neap tide.Scan options: the correct term is absent among A–C.Therefore, among the listed choices A–D, the only acceptable response is “None of the above.”
Verification / Alternative check:
Tide tables clearly show smaller ranges near quarter phases (neaps) and larger ranges near syzygy (springs).
Why Other Options Are Wrong:
Spring tide — maximum range, opposite of what is asked.Low tide — the lower water level within a cycle, not the minimum range term.Ebb tide — outgoing phase of the tide, unrelated to range naming.
Common Pitfalls:
Confusing “low tide” (a level) with “neap tide” (a type of tidal range event).
Final Answer:
None of the above
