Answer:
The melting of the caps increases the concentration of CO2 in the water, making its absorption faster.

Explanation:
<h2><u>CO2 absorption</u><u> </u></h2>
The polar caps of our planet have in their composition several elements, among them the CO2 that is absorbed by the atmosphere. Cold waters, which are present in the Arctic, have an easier time absorbing CO2 compared to other waters.
When glaciers melt, the CO2 that is present in the mixture is dissolved in the ocean, increasing its concentration. The cold waters that came from the ice caps increase the absorption of CO2.

This is most likely corrosion. When pure silver reacts with sulfur chemicals it forms a black coat tarnish (silver sulfide)
The sulfur comes from hydrogen sulfude from air pollution this may result in an increase in mass or you can say: When iron or any other metal oxidizes, oxygen from the air combines with the iron to make iron oxide or rust. So the weight increases, due to the increased weight of oxygen which has combined with the iron either one they are both correct.
