Final answer:
Spring tides are periods of very high and very low tides caused by the alignment of the Earth, Moon, and Sun, not related to the spring season.
Step-by-step explanation:
The correct description of spring tides is that they are the times when very high and very low tides occur due to the alignment of the Earth, the Moon, and the Sun. During spring tides, the gravitational forces of the Moon and the Sun combine to produce the highest and lowest tides. It is a common misconception that spring tides are related to the spring season; instead, the term spring refers to the notion that the tides spring up. On the contrary, neap tides, which occur when the Sun and Moon are at right angles to each other, result in lower high tides and higher low tides.
