In order for a driver to graduate from a learner’s license to an operator’s license, how many hours of driving need to be documented? how many nighttime driving hours are required?

To graduate from a learners license to an operators license you need these steps below.

1.) Must be at least 16 years old.
2.) Hold learners license for 12 months or age 18 (whichever comes first)
3.) Have driven at least 50 hours with learners license (10 of which were at night)
4.) Provide signed Certification of Minor Driving Experience Form.
5.) Passed driving skills test. (The vehicle used for the driving test must have a current registration and be insured.)

I included more information so you can have a much easier time in requiring this upgrade. 
Hope I helped!

Answer arrangement;

Relief sculpture - images are set against a flat background. a coin is a good example: the inscription, the date, and the figure are slightly raised above a flat surface. the ancient egyptians sometimes carved figures into a flat surface.    pro: they take significantly less time to make and do not require as much tools or skills as free-standingcons: not nearly as realistic, as it is not fully 3-d, and does not have the details that a free-standing one does.freestanding sculptures (also called  carved in the round) are not attached to any  background.  they are 3-dimensional  and fully rendered.
