How does chopping a solid up into little pieces change its surface area?

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased: more particles are exposed to the other reactant.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
