Answer to Question 1

The inverse square law states that the flux from an isotropic point source is reduced by the square of the distance from the source to the receiver.

Answer to Question 2

Water vapor absorbs certain longer wavelengths of the solar radiation striking the atmosphere and reradiates it in the thermal infrar ed. (Combustion produces two of the most important greenhouse gases: water vapor and carbon dioxide.
