Final answer:
During the last-quarter phase of the moon, the high tides will be lower than usual. This is because the tides produced by the Sun partially cancel out the tides of the Moon, resulting in neap tides.
Step-by-step explanation:
In the last-quarter phase of the moon, the high tides would be lower than usual. This is because during this phase, the Moon is at a right angle to the Sun's direction, and the tides produced by the Sun partially cancel out the tides of the Moon. These lower tides are called neap tides.
Neap tides occur when the Sun lies at 90° to the Earth-Moon alignment. On the other hand, spring tides, the highest tides, occur when Earth, the Moon, and the Sun are aligned. It's important to note that the height of tides can vary depending on other factors like the geography of the coastline.
