A neap tide has the greatest difference between consecutive low and high tides
Don't know what you are asking, but I hope this will help.
Neap tide, tide of minimal range occurring near the time when the Moon and the Sun are in quadrature. This condition is geometrically defined as the time at which the line from the Earth to the Moon is at right angles to the line from the Earth to the Sun.
To understand why a neap tide has the greatest difference between consecutive low and high tides, it's important to know how tides are formed. Tides are caused primarily by the gravitational forces exerted by the Moon and, to a lesser extent, the Sun on Earth's ocean waters.
During a neap tide, the gravitational pull of the Moon and the Sun on Earth's oceans work against each other. The Moon's gravitational pull is strongest when it is directly overhead or on the opposite side of the Earth (causing high tides), while the Sun's gravitational pull is strongest when it is aligned with the Moon (also causing high tides).
However, during a neap tide, the gravitational forces of the Moon and Sun are at right angles to each other. As a result, the gravitational pull is somewhat balanced, resulting in weaker tides. The high tides are not as high, and the low tides are not as low. This means that the difference in water level between consecutive low and high tides is at its greatest during neap tides.
So, during a neap tide, the gravitational forces of the Moon and the Sun are competing against each other, resulting in a smaller tidal range (the difference between high and low tides) compared to other times.
