What would happen if the moon did not exist?

Question

Clara Avalos · Accepted Answer

If the Moon did not exist there would not be life on Earth as we know it.

Because of the Moon's gravitational pull on the Earth's equatorial bulge, the tilt of the Earth's axis is stabilized to a large extent, keeping it between 22.5 and 24 degrees. Venus has turned upside down due to the pull of the sun and other planets, and the Earth is also pulled by them. If the Moon weren't there, the axial tilt would change drastically. In the worst case scenario, one hemisphere would experience permanent Summer and one hemisphere would experience permanent Winter if the tilt was nearly 90 degrees, as on Uranus.

In my opinion, even in the absence of Moon, there could have been evolution upon the Earth. We would be here to discuss questions like this.

Appropriate levels of solar radiation and an atmosphere with a suitable mixture of gases, such as oxygen and nitrogen, are more important for life to exist on a planet. Sun-oriented tides at aphelion and perihelion would be the only tides that would exist in the absence of the Moon. We would miss the regular spring and neap tides in river mouths, estuaries, and bays, with extremes on New and Full Moon days.

Levi Alexander · Answer

undefined If the moon did not exist, several significant changes would occur on Earth, including alterations to tides, the length of days, and potentially the evolution of life. Tides would be lower and less predictable. The Earth's rotation would also be affected, leading to shorter days. Additionally, the moon plays a role in stabilizing Earth's axial tilt, which affects climate and seasons. Without the moon, Earth's axial tilt might vary more, impacting climate stability.
