The solar nebula acts as a skater spinning on ice it pulled thing closer to the center as it is spinning. The heavier stuff is pulled close to the center of the nebula as it it spinning. In our earth all of the heavy stuff lies in the center forming the core while the lighter areas of our earth moved to the surface making up the crust.
