How do we feel the thermal energy from the sun if there are no particles in space?

THE AMOUNT OF THERMAL ENERGY AND RADIATIONS ABSORBED BY EARTH SYSTEM INCREASES IF THERE ARE NO PARTICLES IN SPACE.

Explanation:

Heat on earth's surface simply move from one part to other part of the surface. About 29 percent of the solar energy that arrives from the top of the atmosphere is reflected back to space by clouds , atmospheric particles , or bright ground surfaces like sea ice and snow. This energy plays no role in earth's climate system.

About 23 percent of incoming solar energy is absorbed in atmosphere by water vapor ,dust and ozone and 48 percent passing through atmosphere is absorbed by surface. Thus about 71 percent of total incoming solar energy is absorbed by Earth system and atmosphere.

since all these particles , atmosphere are reflecting some amount of heat energy back to space but if there are no particles in space the amount of thermal energy that gets absorbed by the earth increases resulting in thermal radiation and health problems such as skin cancers etc..

i think the answer is a and b

i wish you luck
