Questions using tidal range
Problem 1
Which statement correctly uses tidal range in Eclipses & Tides: Alignment with Different Mechanisms?
- Ocean tides are caused by the Moon’s shadow.
- Every new or full phase must produce an eclipse.
- tidal range: The difference between high and low water levels using the same reference.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
tidal range: The difference between high and low water levels using the same reference.
The difference between high and low water levels using the same reference. The diagram represents a possible solar eclipse if alignment is exact. A’s range is 4.5 m and B’s 2.0 m. Tides involve gravitational effects, not a shadow lifting water. The table is fictional and cannot plan a real shore visit, and an alignment drawing does not guarantee an eclipse at every new phase.
