Question

why are high tides higher than normal and low tides lower than normal during a new moon?
the sun’s gravity pulls on the oceans more than the moon’s gravity.
gravity from both the sun and the moon pulls on the oceans from the same side of the earth.
during a new moon, the moon’s gravity doesn’t affect the earth or the oceans.
when the moon’s light is absent, the ocean water temperature decreases drastically and is not affected by the pull of gravity.

Explanation:

1. Analyze the first option: The moon's gravity has a stronger effect on Earth's tides than the sun's (even though the sun is more massive, the moon is much closer), so this is incorrect.
2. Analyze the second option: During a new moon, the sun, moon, and Earth are aligned with the moon between the sun and Earth. So the gravitational pulls of the sun and moon on the oceans are in the same direction (from the same side of Earth relative to the ocean bulges), which combines their gravitational forces, leading to higher high tides and lower low tides (spring tides). This makes sense.
3. Analyze the third option: The moon's gravity always affects Earth and its oceans, so this is incorrect.
4. Analyze the fourth option: Ocean tides are due to gravity, not water temperature changes related to moon's light. This is incorrect.

Answer:

B. Gravity from both the sun and the moon pulls on the oceans from the same side of the earth.
