Final answer:
During a neap tide, the Sun, Earth, and Moon form a 90-degree angle, resulting in less extreme tides due to the perpendicular gravitational forces of the Sun and Moon.
Step-by-step explanation:
The angle that the Sun, Earth, and Moon form during a neap tide is 90°. Neap tides occur when the gravitational forces of the Sun and the Moon are at right angles to each other, which results in the lowest high tides and the highest low tides of the lunar cycle.
During these tides, the Sun's gravitational pull is perpendicular to the Moon's, effectively weakening the overall tidal effect on Earth.
