answer
the cranium of a child is larger than that of an adult.
the ossification and articulation process is complete.
the brain stops growing, and cranial sutures develop.
brain development is incomplete until maturity.
i dont know yet

Explanation:

The skull grows significantly before 5 years of age mainly because the brain is rapidly developing during this period. Once the brain stops growing and cranial sutures develop, skull growth slows down. The ossification and articulation process is not complete before 5 years. Also, the cranium of a child is not larger than an adult's in general terms; it grows to reach adult - like proportions. Brain development is not the reason for significant skull growth before 5 as it implies lack of development, while it's the active development that matters.

Answer:

The brain stops growing, and cranial sutures develop.
