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.
If you just got a really bad hair cut, then hair seems like it does not grow at all, while hair that you have to shave every day seems to grow like a weed! Ignoring these perceptual differences, human hair seems to grow at a pretty consistent rate of about half a millimeter or so per day, or about half an inch every month (this study quotes a specific rate of 0.44 mm per day).
