Hello student.

Hope you are doing well.

As per the data collected, it is said that earlier there were two moons orbiting around the earth before it collided with present day moon.

The lunar havoc would have been increased causing massive tsunami's, earthquakes, volcanic eruptions. But it would have been normal after some time giving some chance for the life tk exist on earth.

For more information, you can read the article present at this link:

Hope this will help you and it solves your query.

Have a great day!

Good luck!!

Hello,

The presence of the moon is the cause of the tidal waves and also the seasons on Earth. Now for instance, let us assume we have two moons.

The gravitational pull that will be experienced by the earth would be greater. The tidal waves would me much higher and will have a huge intensity. The earth's axis would experience the pull which in turn would affect the period of rotation. This will directly affect the day-night duration and the duration of seasons. The seismic activities and volcanic eruptions will also be very frequent and way more deadly than it already is.

If you go ahead to consider the existence of three moons, the shoreline would be impossible to inhabit and the corresponding changes you can very well guess.
