Why does permeable rock weather more quickly?
A permeable rock contains many air spaces, which means it has more surface area than less permeable rocks. Since it has more surface that is exposed to the substances or forces in the environment, weathering is likely to occur at a faster rate in this type of rock.
How is the surface area of a rock related to its rate of weathering?
Large rocks have less surface area for their volume than small rocks. Therefore, a smaller portion of the rock is exposed to weathering. It takes longer for the rock to wear away. The small rock has more surface area for its vol- ume, so it weathers away faster.
Does permeable rock weather easily?
Some rock weathers more easily because it is permeable. Permeable means that a material is full of tiny connected air spaces that allow water to seep through it. Permeable rock weathers chemically at a fast rate. As water seeps through the spaces in the rock, it dissolves and removes material broken down by weathering.
What was the most common rock type of the tombstones in Raleigh Cemetery?

How do you clean a grave plaque?
Vinegar and salt: This easy, simple solution can be cobbled together with ingredients you can find in your home. Simply mix white vinegar and salt together until it forms a paste, then apply to the grave marker. Wait a few minutes, then scrub and wash away the paste. The oxidation should be gone.
