In this item, we are asked to determine the correct definition for the terms. It is unfortunate that they meanings to which we could match them are not given. With that, the answers written here are the well-researched ones.
Solution --> This type of erosion happens when the components found in the rocks (i.e. limestone) are dissolved through the acid components of acid rain.
Abrasion --> This is a process by which the rocks that are eroded to the riverbanks wear down other components of the bed.

Wind and water is the answer
Hope this helps!
