12. when checking ids, what information on the bc novice (n) and learners (l) type driver's licences identify drivers licence holders under the age of 19 easily?

When checking ID cards, either it is N or L,  the easiest and fastest way to check someone's age is with the date of birth given on the front of the drive licence. With this, you can know exactly when the person was born and check their age, either they are under 19 or older.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
