The Dark of the Moon

Finn

Tides would be almost non-existent. During Full Moons and New Moons, which occur when the sun, Earth and moon are all aligned, we have spring tides, which are the largest differences between high and low tide.

When they’re at right angles, which happens during a Half Moon phase, we have neap tides, which are the smallest differences.

It’s the moon that exerts the greatest forces on the oceans, so if we had no moon, we would only have small neap tides all the time.

I can now add another item to the list, which is that Philly wouldn’t have been able to fly to France and back on her secret mission if there hadn’t been a big enough moon for the Lysander pilots to navigate by. So all in all, the moon is pretty cool.
