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.
Hair is actually a modified type of skin. Hair grows everywhere on the human body except the palms of the hands, soles of the feet, and lips. Hair grows more quickly in summer than winter, and more slowly at night than during the day. Like hair, nails are a type of modified skin â and they're not just for beauty.
