To determine which conditions can lead to an extremely low low tide during the occurrence of extremely high high tides, we need to understand the concepts of apogee, perihelion, aphelion, and the phases of the moon.
1. Apogee and Perigee: Apogee refers to the point in the Moon's orbit when it is farthest from the Earth, while perigee refers to the point when it is closest to the Earth. When the Moon is at perigee, it exerts a stronger gravitational pull on the Earth, resulting in higher tides. Therefore, we are looking for conditions where the Moon is at perigee.
2. Aphelion and Perihelion: Aphelion represents the point in Earth's orbit when it is farthest from the Sun, while perihelion represents the point when it is closest to the Sun. These orbital positions of the Earth do not have a direct impact on the tides.
3. Phases of the Moon: The phases of the moon can influence the tidal range. During a new moon or a full moon, when the Sun, Earth, and Moon are aligned, we have higher high tides and lower low tides, known as spring tides. Conversely, during a first quarter or last quarter moon, when the Sun and Moon are at right angles to each other, we experience lower high tides and higher low tides, known as neap tides.
Using this information, we can evaluate the given options:
- Apogee, perihelion, last quarter: This option includes last quarter, which corresponds to neap tides. Neap tides are characterized by lower high tides and higher low tides. This option seems plausible.
- Apogee, aphelion, new moon: This option includes new moon, which corresponds to spring tides, not neap tides. Hence, this option is less likely.
- Perigee, perihelion, full moon: This option includes the full moon, which corresponds to spring tides. Therefore, this option is less likely.
- Perigee, aphelion, first quarter: This option includes first quarter, which corresponds to neap tides. Neap tides result in lower high tides and higher low tides. Thus, this option seems plausible.
Based on the explanations above, the conditions that can lead to an extremely low low tide during the occurrence of extremely high high tides are apogee, perihelion, and last quarter.
