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.
Nails, like hair, grow from the matrix. As older cells grow out, they are replaced by newer ones, they are compacted and take on a hardened form. The average growth rate for nails is 0.1 mm each day; individual rates depend on age, time of year, activity level, and heredity. Fingernails grow faster than toenails.
