equal areas of which type of earth surface will absorb more insolation and radiate more energy back toward space in the same amount of time?

The missing options are

  (1) light colored and rough

  (2) dark colored and rough

  (3) light colored and smooth

  (4) dark colored and smooth

(2) dark colored and rough

Explanation:

The dark color would absorb more radiations and rough surface will further faciliate in absorbing. This is because, dark color absorbs all types of wavelengths (of light) and reflects none of them. This is the reason that it appears black. Rough surface will increase the surface area and thus provide more opportunities for absorption as compared to the smooth surface. If the absorption rate would be higher, than the rate of radiating energy back to the space would also be higher for the dark and rough surface area. White color and smooth would not be able to absorb because they will reflect all types of wavelengths immediately without storing anything.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
