Limestone Features

Limestone is a sedimentary rock which is formed underwater Some limestone consists mainly of coral or the shells of other small marine creatures Limestone may also be precipitated from seawater Limestone is a permeable rock This means that water can enter limestone through pores joints or cracks in the rock

How Does Weathering Affect Limestone?

Limestone is a sedimentary rock created from the remains of dead sea creatures and is predominately made up of calcium carbonate Many horizontal and vertical cracks run through limestone These cracks allow water to pass easily through the rock Water acts as an acid when it contacts calcium carbonate

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 Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere

Origin of Limestone Caves

Although solution was a major process in the formation of limestone caves some major problems are encountered if these caves are considered to have formed only by solution The first problem is the origin of the original fracture porosity along which circulation of acidic groundwater could be initiated

Limestone

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%) It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite) Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are

What is Quicklime and How is it Made?

After the limestone rocks are processed they are transported to a lime kiln for calcination This is the process where the limestone is heated to a temperature above 1 472F for decarbonation i e removal of carbon dioxide in gaseous form to produce quicklime Almost half of the limestone

How is limestone formed?

The joints in a massive limestone area are important because they form zones of weakness in the rock which are attacked by acidic rainwater and chemically weathered Coral limestones Perhaps the type of limestone that many people think of first is the coral reef which can be seen growing in the world's warmer shallow ocean margins

The Origin of Limestone

The acid combines with the limestone to release fizzing bubbles of CO 2 gas As you will see limestone and CO 2 gas are intimately related Another common chemical reaction involving limestone begins when CO 2 dissolves in water forming a weak acid (carbonic acid)
