Question

explain why neap tides are less extreme than spring tides.
neap tides occur when the earth is farthest from the sun.
neap tides occur when the gravitational forces of the sun and moon are combined.
neap tides occur when the gravitational forces of the sun and moon partially cancel each other out.
neap tides occur when the earth is closest to the moon.

Explanation:

To determine why neap tides are less extreme, we analyze the tidal forces:

• Spring tides occur when the Sun, Moon, and Earth are aligned (new or full moon), so the gravitational forces of the Sun and Moon combine, leading to more extreme tides (higher highs and lower lows).
• Neap tides occur during the first and third quarter moons, when the Sun and Moon are at right angles relative to the Earth. In this configuration, the gravitational pull of the Sun partially counteracts (cancels out) the gravitational pull of the Moon. This partial cancellation results in less extreme tidal ranges (lower highs and higher lows) compared to spring tides.

Now let's evaluate the options:

• Green option: The distance of Earth from the Sun is not the primary factor for neap tides. Eliminate.
• Purple option: Combined forces happen in spring tides, not neap tides. Eliminate.
• Orange option: This matches the explanation of partial cancellation of Sun and Moon's gravitational forces during neap tides. Correct.
• Blue option: Earth's closeness to the Moon is not the reason for neap tides (and is more related to perigee, not neap tide timing). Eliminate.

Answer:

Orange. Neap tides occur when the gravitational forces of the Sun and Moon partially cancel each other out.
