No, a large presence of humans on the Moon and the Coriolis effect would not cause a dust cloud to form around the Moon's equator. The formation of a dust cloud around the Moon is not influenced by human activity or the Coriolis effect, but rather by natural processes specific to the Moon's environment.
Dust on the Moon primarily originates from micrometeoroid impacts, which are small particles from space colliding with the lunar surface. These impacts release fine particles of dust, known as regolith, into the lunar environment. Over time, the regolith can be further broken down into finer dust particles due to micrometeoroid impacts, solar wind, and electrostatic charging.
The Moon's lack of atmosphere and its weak gravity allow dust particles to remain suspended for longer periods compared to Earth, creating a thin layer of dust near the surface. However, this dust tends to be globally distributed rather than concentrated around the Moon's equator.
While a significant human or machine presence on the Moon could disturb the lunar regolith through activities such as excavation, movement of vehicles, or construction, it is unlikely to generate a persistent dust cloud around the equator. The disturbance caused by human activity would likely be localized and limited to specific areas, and any resulting dust would disperse and settle relatively quickly due to the Moon's low gravity and lack of atmosphere.
In summary, the formation of a dust cloud around the Moon's equator is primarily driven by natural processes related to micrometeoroid impacts and not influenced by human activity or the Coriolis effect.
