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.
Luckily, scientists have. Fingernails grow a little over twice as quickly as toenails: an average rate of 3.47 mm/month compared to 1.62 mm/month [1]. Nails evolved from claws about 55 million years ago, and are one of the features that distinguish primates [2].
