Why are some lakes more affected by acid rain than others?
What will be an ideal response?
How a lake is affected by acid rain has a lot to do with the chemical composition of the lake bed. Lakes sitting on top of a bed of limestone (calcium carbonate), for example, are not so affected by acid rain because any incoming acid is neutralized by the limestone, which behaves as a base. A lake lined with granite, however, has no such protection and is thus more affected by unduly acidified rain.
