erosion of the marble
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 effects like erosion from wind, rain, and temperature changes, as well as biological growth like moss or lichen, can cause the inscription on a marble gravestone to fade or become harder to read over time. Additionally, pollution and air quality can contribute to the deterioration of the stone and make the inscription less legible.
Most inscriptions are cut into the marble gravestone, and then gilded with either gold leaf or gold paint. Subjected to the heat of summer and the cold of winter, and rain, an inscription is subjected to severe weathering.
Weathering and erosion caused by exposure to elements like rain, wind, and sunlight can wear down the surface of the marble, making the inscription harder to read over time. Additionally, biological growth such as moss, lichen, or algae can accumulate on the stone and obscure the text.
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
Exposure to harsh weather conditions such as rain, wind, and sunlight can erode the marble and cause the inscription to fade. Additionally, natural processes like moss and lichen growth can cover the inscription and obscure it over time.

A marble gravestone becoming difficult to read over time in an area with high pollution is primarily due to chemical weathering. The pollutants in the air can react with the marble, causing it to deteriorate and lose its clarity, making the inscription harder to read.
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.
