I believe that it loses energy, as it is moving away from the main power/control source.
In a endothermic reaction energy from an outside source is continuously being added.
Right answer is option d that o is oxidized.
Acid rain slowly dissolves rocks due to chemical reactions between the acid and the minerals in the rock. Differential Weathering: Softer, less resistant rocks wear away at a faster rate than more weather resistant rocks. More exposure to acid rain results in more rapid weathering.
