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.
