How do ancient maps of the middle east differ from modern maps of the region?

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.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
