Neap tides are a type of tide that occurs when the gravitational pull of the sun and the moon are perpendicular to one another, resulting in a weaker tidal range. Option 2, "Weak," is the correct answer. During neap tides, the high tides are lower and the low tides are higher compared to normal tides, resulting in a smaller difference between high tide and low tide. This occurs because the gravitational forces of the sun and the moon partially cancel each other out. Neap tides occur twice a month, during the first and third quarter moon phases. It is important to note that neap tides are the opposite of spring tides, which are characterized by a stronger tidal range. Therefore, option 1, "Strong," option 3, "Medium," and option 4, "Very strong," are incorrect.
