D is not correct because the atmosphere doesn't expand, C isn't correct because the Sun doesn't heat all the Earth evenly (hence different climates), B is not correct because cold fronts can be singular, so it has to be A

There is a significant correlation between carbon emission and soil quality, as it has been proved that when one increase, the other those that too, because of the multiple beneficial effects that minor carbon emission have on the whole eco system. Those benefit can be different but the result will be almost the same.
