Final answer:
A neap tide occurs when the sun, moon, and earth form a right angle, with the sun at a 90° angle to the Earth-Moon alignment, leading to moderately high and low tides.
Step-by-step explanation:
What type of tide occurs when the sun, moon, and the earth are in the right angle? The correct answer is B. Neap tide. Neap tides occur when the gravitational forces of the Moon and the Sun are perpendicular to one another relative to Earth. This happens when the Sun lies at a 90° angle to the Earth-Moon alignment. During neap tides, the high tides are lower and the low tides are not as low as they are during spring tides.
On the other hand, spring tides, which represent the largest tides, occur when Earth, the Moon, and the Sun are aligned, with the gravitational pulls of the Moon and the Sun reinforcing each other, resulting in higher high tides and lower low tides.
