Q. Consider the following statements with reference to the spring tides and neap tides:
- Neap Tides occur when Moon is a quarter phase
- Spring tides occur on Full Moon as well as New Moon
- Spring tide has higher than normal high tides and lower than normal low tides
- During the Neap Tides, the high tide is lower and the low tide is higher than usual
Which among the above statements is / are correct?
Answer:
1, 2, 3 & 4
Notes:
- Neap Tides occur when Moon is a quarter phase - Correct. Neap tides happen when the Sun and Moon are at right angles to each other, which occurs during the Moon's quarter phases.
- Spring tides occur on Full Moon as well as New Moon - Correct. Spring tides occur during the new moon and full moon phases when the Sun, Moon, and Earth are aligned, leading to enhanced tidal ranges.
- Spring tide has higher than normal high tides and lower than normal low tides - Correct. The gravitational alignment during spring tides leads to extra high high tides and extra low low tides.
- During the Neap Tides, the high tide is lower and the low tide is higher than usual - Correct. With the Sun and Moon at right angles, their gravitational forces partially cancel out, leading to smaller tidal ranges with lower highs and higher lows.
