Question

1. infer recall the snowy beach from the beginning of the chapter. how do the positions of the sun and the moon affect the ocean tides at this beach? fsas sc.8.e.5.9 when the sun and moon are aligned 2. enter your answer. compare why is the water level of a low neap tide different than the water level of a spring tide? fsas sc.8.e.5.9

Explanation:

Step1: Recall tide - generating forces

The gravitational forces of the Sun and Moon on the Earth's oceans cause tides. When the Sun and Moon are aligned (during new - moon and full - moon), their gravitational forces combine.

Step2: Analyze spring tides

The combined gravitational pull of the Sun and Moon during alignment leads to higher high - tides and lower low - tides, known as spring tides.

Step3: Recall neap tides

When the Sun and Moon are at right angles to each other (first - quarter and third - quarter moons), their gravitational forces partially cancel each other out.

Step4: Analyze neap tides

This results in lower high - tides and higher low - tides, known as neap tides. So, the water level of a low neap tide is higher than the water level of a low spring tide because the combined gravitational pull is weaker during neap tides.

Answer:

1. When the Sun and Moon are aligned (during new - moon and full - moon), their combined gravitational pull causes higher high - tides and lower low - tides (spring tides) at the beach.
2. The water level of a low neap tide is higher than the water level of a low spring tide because during neap tides, the Sun and Moon are at right angles to each other, and their gravitational forces partially cancel each other out, resulting in weaker tidal forces overall.
