Homework Statement
why moon has no atmosphere?
The moon doesn't have an atmosphere because it has a weak gravitational pull. This means that it is unable to hold onto gases in its atmosphere, which leads to them escaping into space.
The lack of atmosphere on the moon means that it has no protection from solar radiation, meteoroids, and other space debris. This results in the moon's surface being constantly bombarded and causing the formation of craters.
Yes, the moon's lack of atmosphere means that it has no way to trap heat, leading to extreme temperature fluctuations. During the day, the surface can reach up to 127 degrees Celsius, while at night, it can drop to -173 degrees Celsius.
It is believed that the moon may have had a thin atmosphere in the past, but it was likely lost due to the same reasons as its current lack of atmosphere. However, there is ongoing research and exploration to understand the moon's history better.
The moon's lack of atmosphere makes it inhospitable for life as we know it. Without an atmosphere, there is no protection from harmful radiation and extreme temperatures, making it impossible for life to survive on the moon's surface.
