Not necessarily an academic question but it is life skills i just turned 18 and i want to buy a motorcycle from my friends' dad. clean title, everything is good. i just don't know how to get insurance or put the title in my name. . i already know how to get a motorcycle sponsorship i just dont know how to do therest of the adult stuff

Okay, so I'm assuming you have a motorcycle permit, and a license and all that. Also remember, it depends on what state you are in. So, in a complete assumption, say you live in America. Examples of insurance companies would be like GEICO, or Progressive (I've been told those are the good ones). You would have to then get a quote. After doing that, you would need to verify that you have a valid license plate and all that. After that, I believe you would be good to go. If you live in another country, and this wasn't helpful, let me know, and I can give you a correct answer for wherever you live. 

Ithink b hope that

If you are talking about typical sand you would find at the beach or in a river bed here on earth, there are some differences. i would say the first biggest difference is in composition and mineral make up. although the moon is largely made of the same materials as earth’s mantle and surface, the moon experiences very little weathering (no liquid water and virtually no atmosphere). “earth” sand is typically composed mostly of quartz grains. this is because quartz is highly resistant to both physical and chemical weathering. most of the other minerals originally with the quartz are broken down into fine clay and carried away, chemically eroded/ dissolved, or some combination of the two. this usually leaves only the quartz behind, and so most of the time when you see/think of sand, you are talking about quartz. without these weathering mechanisms on the moon, the “sand” (which is likely more silt or clay sized grains anyways) would consist of mostly other minerals like anorthosite, olivine, and proxene.
