Inscriptions can be blurred on monuments due to several factors :s

Because your brain doesn't make new connections between the nerve cells as fast as it did when you were young.
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
They bury nuts, for use in harder times, and they do not always find all of them, so some germinate and become plants.
No. Slate is harder. Slate is shale that has been heated and compressed.
Why is quartz harder steel
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.
Erosion not erosion . The answer it Chemical Weathering..............:-)hismejohn
EROSION. Not erosion . The answer it chemical weathering............;-)hismejohn
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
In general they have got sleeker, faster, more capacious and much harder for the amateur to repair.
When bacteria become resistant by adapting to their environment they become harder to treat.

Work harder. "The harder I work, the luckier I become."
Twice a day, do sit-ups for three minutes. Overtime, you'll get better. I can do about 65 sit-ups per minute.
Work harder
