If the Earth had no Moon, what changes would be immediately noticeable? Choose ALL the correct answers!
Without Earth's tilted axis from the collision that created the Moon, we would not have seasons on Earth.
Without the Moon's gravity to stabilize Earth's tilt, our axis would shift.
Nights would be absolutely black with darkness.
