Gravestones used to made out of all kinds of materials but it was found that they are not durable and don't withstand the weather. Nowadays, most gravestones are made of granite or marble because these are more durable and withstand time.
Marble is a durable stone with small porosity which is why it is often used for gravestones and memorials as well as architecture. Deterioration comes from simply from weathering (rain, snow, wind) and it is sped along by a mixture of the moisture with atmospheric pollutants and temperature. Currently, scientists are evaluating gravestones in order to measure the history of acid rain in a project called the "Gravestone Project".
Marble is a metamorphic rock. It is a metamorphism of limestone or dolostone and contains calcite and dolomite.
Hi. Gravestones are meant to last for centuries to provide a lasting memorial; however, some gravestones have deteriorated because of weathering which can actually destroy the stone or make the inscriptions unreadable. If a gravestone is made out of durable material, like marble or granite, it will be somewhat weather resistant and the inscriptions will remain readable for centuries. We have chosen these materials for our line of gravestones and memorials to ensure that they will be enduring memorials.

Weathering and erosion from exposure to the elements, such as rain, wind, and UV rays, can cause the inscription on a marble gravestone to fade and wear down over time. Additionally, the growth of moss, lichen, and other organisms on the surface of the marble can obscure the inscription and make it harder to read.
Weathering from natural elements such as rain, wind, and sun exposure can cause erosion and fading of the inscription on a marble gravestone over time. The accumulation of dirt, moss, and lichen can also obscure the text, making it harder to read.
The most important contributor to the erosion of marble gravemarkers is acid rain. Normal rain erodes marble also, but at a much slower rate than acid rain.

Inscriptions can be blurred on monuments due to several factors :sChemical weathering in which acid rain containing carbonic acid, sulphurous acid or nitrous acid chemically attacks the stoneThermal damage from hot sunlightFrost damage from water entering and freezing in small cracksPhysical erosion from sand and dust blown at the surfacePhysical erosion from passersby touching the inscription

Marble is not a very robust stone. In terms of natural causes, marble is easily dissolved by acids - even relatively mild ones - so acid rain is one possible cause. Erosion by wind blown sand other other small particles is another.
A gravestone can be made from any hard wearing stone such a granite or marble.

Simply rain, gravestones are frequently made of marble and marble is etched by rain.
