The Moon of the Earth has some similarities, but also lot of differences with the other natural satellites in the Solar system.
The Moon is rocky, covered with dust, has lot of craters from asteroids and meteorites. Most of the planets in the solar system are actually gassy, frozen, and the craters tend to be very rare.
Compared to the planet around which it spins, the Earth, the Moon is actually very large, even though it is nowhere as large as some other moons in the Solar System. All the other moons tend to be much smaller in comparison the the planets around which they spin.
The Moon also has very low gravitational pull and very small mass for its size, and the reason for that is still not clear. All the other moons have gravitational pulls and masses that are expected by their size.
Technically, none. The answer is a volcanic eruption.
Agriculture can prove extremely difficult to maintain on a rocky mountain and with such poor infrastructure it is also difficult to import goods on a JIT (Just In Time) sort of basis where you receive these goods as you need them. Infrastructure also includes communication and other services and with such a technologically developed era we depend on technology and this can deter a lot of people from settling in these regions, additionally the wildlife in these regions consists greatly of predators which can be deemed a threat to habitants who are unprepared. The sheer abundance of wildlife and non industrial landscapes can also mean that people will not want to live in these regions
Different populations living together make up a community.
