One term that is used is osteogensis. It means to make (-genesis) bone (osteo-). Another term is osteosis.
Bone starts as cartilage in the fetus. As the fetus takes on the final shape, this cartilage arranges, and enough hardening occurs in the limbs to allow the creature to stand shortly after birth. At that point, all the bones begin to harden, and continues to harden all throughout life. Bones contain a level of cartilage all the way until old age.

Oh gosh no. A child has much more cartilage because a fetus has no bone this is to fit through the birth canal. It takes a child many years for their cartilage to become bone. This is why children have less broken bones than adults. They have not fully converged from cartilage to bone
Cartilage is a precursor to bone in developing fetuses and any cartilage left over after birth (ie in ears and nose) is to provide structure and shape to something. Without ear cartilage, the ear might be floppy and not work to catch sound waves. Cartilage can also help to protect joints by providing a cartilage cushion between two bones in a joint. Your knee is a good example of this - cartilage inside the knee absorbs impact whenever your foot hits the ground and prevents wear and tear on the bones of the knee joint.
