Coconut palms continue to produce roots from the base of the stem throughout their lives. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that is 60 to 70 years old.
Albedo (/Ã¦lËbiËdoÊ/) is the whiteness of a surface. It is a reflection coefficient, and has a value of less than one. Albedo is derived from Latin albedo whiteness (or reflected sunlight) in turn from albus white, is the diffuse reflectivity or reflecting power of a surface. The albedo of a surface is the ratio of radiation reflected from the surface to the incident radiation. Its dimensionless nature lets it be expressed as a percentage and is measured on a scale from zero (no reflection) of a perfectly black surface to 1 for perfect reflection of a white surface.
The balance between energy absorbed by the earth and energy reflected back into space is fundamental in determining how warm or cool the planet becomes. The proportion of radiation reflected away by a surface is called its albedo. Albedo can range between 0 (no reflectance) and 1 (complete reflectanceâlike a mirror). The earthâs average albedo is .31, which means that, overall, the planet reflects about 31% of incoming solar radiation back into space.
