What could be the potential reasons for the loss of legibility in these gravestones?

Chemical Weathering – e.g dissolution by acid rain. Physical Weathering – e.g. freeze thaw action. Biological Weathering – e.g lichen growth.

What types of weathering would act on a gravestone?

Chemical Weathering

Oxidation is caused by iron in the stone oxidizing or rusting when water and air are present. This causes stains to the gravestone and can often be seen as the orange/yellow/brown patina on sandstones due to their mineral content.

Which of the following is the result of chemical weathering?

Chemical weathering changes the molecular structure of rocks and soil. For instance carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid called carbonic acid that can dissolve rock.

Where do grave stones come from?

In recent years it is most common to find granite headstones that are built to last forever. The granite for each modern memorial comes from quarries all around the world in countries such as Canada India China and Sweden.

How long should lettering on a headstone last?

Marble was one of the first types of stone to be imported for use as memorials and for sculpture. But it tends to erode when exposed especially in salty air or acidic rain. However provided lettering is carved into the marble materials properly it should still be readable for many years.

Cenotaph – a grave where the body is not present a memorial erected as over a grave but at a place where the body has not been interred. A cenotaph may look exactly like any other grave in terms of marker and inscription.

What were old headstones made of?

Most gravestones made over the last few centuries are made of a few types of rock: marble slate and granite are the big three. Sometimes you run into darker stones made of gabbro maybe a few sandstone markers but especially in more recent monuments marble and granite (and other plutonic rocks) rule the roost.

The reason is most likely algae lichen moss mold or mildew growth and stains. These growths develop on the surface making headstones and memorials look dark and dirty. The majority of monuments sit outside and are constantly subjected to moist humid conditions.

Which of the following can cause physical weathering?

Pressure warm temperatures water and ice are common causes of physical weathering.

What are examples of weathering?

Weathering is the wearing away of the surface of rock soil and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain. Weathering can occur due to chemical and mechanical processes.

What is the most commonly used rock for tombstone markers?

Granite

Granite began to be used for markers in 1860 and is the most commonly used marker material in use today. All of the markers in the sample image are made of granite. Limestone is calcite and ranges from pure white to brown.

How do plants cause weathering?

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow they widen the cracks eventually breaking the rock into pieces. Over time trees can break apart even large rocks.

How does weathering affect limestone?

Weathering is the breakdown of rock by physical chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone. This causes the limestone to dissolve.

How do animals cause erosion?

Animals cause erosion in other ways too. When too many animals live in one place they tend to eat and trample all the plants. Without the plants to protect the soil it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.

What causes erosion?

Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice. … The key to erosion is something called “fluid flow.” Water air and even ice are fluids because they tend to flow from one place to another due to the force of gravity.

How does Frost cause weathering of rocks?

Frost action is an effective form of mechanical weathering. When water trickles down into fractures and pores of rock then freezes its volume increases by almost 10 percent. … Frost action causes rocks to be broken apart into angular fragments.
