* Granite is harder and more resistant to weathering: Granite is a very hard igneous rock, with tightly interlocking crystals. This makes it more resistant to physical weathering (like abrasion from wind or rain) and chemical weathering (like acid rain).

* Limestone is softer and more susceptible: Limestone is a sedimentary rock, often made from the accumulation of shells and other marine organisms. It is softer and more porous than granite, making it more vulnerable to both physical and chemical weathering.

In summary: The granite statue's hard and dense composition will allow it to withstand the elements much longer than the limestone statue, which will be more easily eroded and worn down over time.
