What would be different on earth if the moon did not exist?

Answer 1

If the moon did not exist, several significant changes would occur on Earth. Tides, which are primarily caused by the moon's gravitational pull, would be much weaker or possibly non-existent. The moon also helps stabilize Earth's axial tilt, so without it, our planet's tilt could vary more widely, leading to more extreme climate changes. Additionally, the moon plays a role in the length of our days and months, so our calendar system and the length of our days would be different without it.

Answer 2

If there were no moon, there would be no tides. There would also be complete darkness at night, except for starlight.

Astronomy would probably be less advanced if there never was a moon. The sight of the moon has excited wonder and curiosity throughout the ages.

The moon is slowly drifting away from the earth and was once a lot closer but, at less than 4 centimeters a year, it won't be leaving anytime soon!

Answer 3

This would depend on the reason for the lack of phases. If it was because the moon (for some reason) stopped revolving around the earth, the moon would either crash into the earth or eventually fall into the sun, depending on the moon and earth's respective velocity vectors. However, if we posit a moon orbiting around the earth perpendicular to the plane of earth's orbit around the sun, then the moon would be at a permanent half phase.

Answer 4

Without the moon, Earth's axis tilt could vary more, leading to less stable seasons. Tides would be much weaker, impacting marine life and coastal ecosystems. The moon also helps stabilize Earth's rotation, so without it, days could be shorter and the planet's climate could be different.

Answer 5

we would have no tides. ocean currents would be drastically changed and that would totally change the climates of earth.

Answer 6

It would, on average, be darker at night. And the tides would be smaller and occur at the same time each day.

Answer 7

Tides would be smaller (though not absent; there would still be a solar tide about half as large) and the day would be a bit shorter. Beyond that it's all conjecture.
