0.47
B
0.51
C
0.66
D
0.87
Correct Answer: 0.47
Roughly, 0.47 percent of insolation reaches the Earth's surface. The rest is either reflected and scattered back to space through its interaction with clouds, water vapour, dust and pollen, known collectively as aerosols or it is absorbed by clouds and gaseous elements and hence heats the atmosphere.
