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.
Do All Nails Grow Same Rate. Each individual nail grows at its own pace. Usually, the longer the outermost finger joint, the faster the nail grows. The nail of the index finger thus grows quickly, while the thumbnail grows the slowest, as the thumb lacks the central of the three ordinary finger joints. On the toes, which are shorter than the fingers, the nails grow around three times as slowly.
