Without the moon, the Earth’s tides would be greatly reduced. Shorelines would function more like lakes than oceans. This doesn’t change 99% of the continent, but would have a huge effect on the edges.

The moon is also responsible for stabilizing Earth’s tilt. Without it, Earth’s seasons would be different. Instead of four seasons to a year, we would have many more. This would make the habitable zone of the planet smaller, though being near the equator would still be safe.
