reflectivity
- n the fraction of radiant energy that is reflected from a surface
- n the ability to reflect beams or rays
- n the capability of quiet thought or contemplation
- Since the Earth itself reflects about 30% of sunlight back into orbit, increasing the reflectivity of the planet just slightly could be enough to counter warming.
- At the same time, as the polar icecaps shrink, the planet's total reflectivity decreases.
- The composition and reflectivity of the bodies suggest they were formed within the first 3 million years of the solar system's life, whereas Earth was something of a late arrival .
