Answer:
C. Constant burning of fossil fuels at power plants increases carbon dioxide concentrations in the atmosphere, resulting in faster input of carbon into the atmosphere than the ocean and land can take up.
Explanation:
Nutrient cycling is the process that allows for a continuous and balanced exchange of nutrients between the earth, living beings and the atmosphere. This exchange allows life on earth to be allowed and managed. An imbalance in this exchange can cause very harmful effects that damage the entire system that the earth maintains.
An example of this is the imbalance caused by the excess burning of fossil fuels. That's because the constant burning of fossil fuels in power plants increases concentrations of carbon dioxide in the atmosphere, resulting in a faster entry of carbon into the atmosphere than the ocean and land can absorb.
<span>The answer is definitely C. The
Midwestern United States is an example of a vernacular region. Indeed, the
Midwestern has been generally acquainted and explained by both travelers and
habitants quite mistakenly (most of them characterize the region as some little
town and so on). Moreover, the vernacular element can also be found by paying
attention to the emotional charges these people display while talking about the
Midwestern (most of them knows everybody in town and they have still ongoing
things with some of the city residents). </span>
<span>A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel, monitoring the process to detect when the concentration of aqueous ammonia in the second reaction vessel has fallen below the selected range, and feeding aqueous ammonia solution with an ammonia concentration in or above the selected range to the second reaction vessel to return the solution to within the selected range.</span>
