Answer:

Are you not a resident of the United States? From some other country maybe? You can travel anywhere in the United States without a passport or any thingYou only need a passport if you go outside the United States.
I do not believe you need a passport unless traveling out of th countryHowever, it would be good to have at least two forms of identification with you(e.g driver's license and work ID) for security reasons.
If you're a US citizen, you don't need anything but a photo id to travel between US statesYou'll need a photo id for everyone flying so you might want to make sure that all the kids have either a valid school id, state issued id card, or child id card from your local police department with their name and pictures on themThe id has to be valid and issued by a government agency (such as a school, police department or state office)Good luck and happy travels!
People are free to travel within the United States without a passportA passport is only needed to travel to another countrySince you and your friend aren't old enough to drive, you must be traveling by bus or planeTo travel by bus I don't think you'll need anything to buy a ticketTo travel by plane you'll need a picture ID and because of your age you'll also need a letter from your parents giving permissionHappy Travels Girls.
denierIt's French, I think Denier is a unit of measure for the linear mass density of fibersIt is defined as the mass in grams per 9,000 metersIn the International System of Units the tex is used instead (see below)The denier has its standard based in nature, a single strand of silk is one denierTherefore, a sampled 9,000 meters length of silk will weigh one gramThe term denier is a literal combination of the words linear and densityThe term micro-denier is used to describe filaments that weigh less than one gram per 9,000 meter lengthOne can distinguish between Filament and Total denierBoth are defined as above but the first only relates to a single filament of fiber (also commonly known as Denier per Filament or D.P.F) whereas the second relates to a yarn, an agglomeration of filamentsThe following relationship applies to straight, uniform filaments: D.P.F Total Denier / Quantity of Uniform Filaments The denier system of measurement is used on two and single filament fibersSome common calculations are as follows: 1 denier 1 gram per 9 000 meters 0.05 grams per 450 meters (1/20 of above) In practice measuring 9,000 meters is both time-consuming and wastefulUsually a sample of 900 meters is weighed and the result multiplied by 10 to obtain the denier weightA fiber is generally considered a microfiber if it is 1 denier or lessA 1-denier polyester fiber has a diameter of about 10 micrometersDenier is used as the measure of density of weave in tights and pantyhose, which defines their opaqueness.
