The yellow is the region where fluid flow from the Earth's outer core is the greatest. Red mush is the inner core boundary. Large flows exist on an imaginary tangent cylinder due to the effects of the Earth's rotations, fluid viscosity and the presence of the solid inner core within the spherical shell of the outer fluid core.
Growth Rates. Fingernails grow approximately 2 to 3 millimeters, or about 1/8 inch, per month. Toenails grow slower than fingernails, at a rate of about 1 mm per month. Hair, on the other hand, grows at a much faster rate: roughly Â¼ to Â½ inch per month, or 6 inches per year. In fact, after bone marrow, hair is the fastest growing tissue in the body.
Torn or Detached Nail Facts. 1  Fingernails and toenails, like hair, are composed of protein and fat and are not live tissue. 2  Nails grow a bit more than one-tenth of an inch per month and require three to six months to completely regrow. (Toenails grow more slowly than fingernails.) Nails are produced by the nail matrix cells that reside in the moon shaped whitish area (lunula) at the base of the nail.
