How have humans changed the Sahara desert

Humans have indirectly impacted the Sahara with their increasing growing ecological footprint. The temperatures of the early are rapidly increasing. There is an increase in infrared radiation escaping from the atmosphere into space. An indirect measure of how much heat is being trapped.

the correct answer is c

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
