Explanation / Answer
2.A. Coal burning in the mid-western states.
The dust from the mod-western states is brought to eastern states by the prevailing wind direction.
3.A. Confined
4. the sun.
The ultimate source is the radioactive decay but its not in options and
5. The cycle through which the carbon is exchanged in biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth is known as carbon cycle. This is a biogeochemiical cycle. Since the industrial revolution the carbon dioxide in the atmosphere is 39% increased in the atmosphere.This shows that the carbon exchange is largely impacted by the use of fossil fuels and after industrial revolution we are producing more and more carbon footprints.
