Mrs. Smith did some traveling over the summer.  She visited monuments in both Juneau, Alaska and Hilo, Hawaii.  She noticed that the monuments, both made of Indiana limestone, looked slightly different.  The monument in the Hawaii appeared to have a much higher degree of weathering than the monument in Maine.  Mrs. Summers knows that both cities have the same average rainfall over the year, so what could account for the difference she saw?

• lower RAINFALL in Alaska causes SLOWER weathering

• higher RAINFALL in Hawaii causes FASTER weathering

• higher TEMPERATURES in Hawaii cause FASTER weathering

• NONE of these.
