Sudden Infant Death Syndrome (SIDS), according to a definition on the Mayo Clinic website, is the unexplained death, usually during sleep, of a seemingly healthy baby less than a year old.. The cause is still unknown, but it does not appear to be suffocation, according to the SIDS Network.
Albedo (/Ã¦lËbiËdoÊ/) is a measure for reflectance or optical brightness (Latin albedo, whiteness). It is dimensionless and measured on a scale from zero (corresponding to a black body that absorbs all incident radiation) to one (corresponding to a white body that reflects all incident radiation).
Earthâs Albedo and Global Warming This interactive activity adapted from NASA and the U.S. Geological Survey illustrates the concept of albedoâthe measure of how much solar radiation is reflected from Earth's surface. The balance between the amount of solar radiation reflected and absorbed by Earth's surface plays an important role in regulating global temperature.
