One reason why limestone is susceptible to chemical weathering because when acid acts on the calcium carbonate in the limestone to form calcium bicarbonate which is dissolved by water, which results in pits and holes found in the limestone.
Equations to represent: CaCO3 + H2O + CO2 results in Ca(HCO3)2
What else can I help you with?
Can limestone be worn away?
Yes, limestone can be worn away over time through processes like erosion and weathering. Physical forces such as wind, water, and ice can gradually break down limestone rocks, leading to their erosion and the formation of features like caves, sinkholes, and limestone pavements.
What kind of weathering has created most limestone caves?
chemical weathering called karsting and it createskarst topography. ... Dissolution of soluble limestone creates limestone cavessource yahoo answers
Is limestone cave formation chemical or mechanical weathering?
chemical change
Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Why is a limestone in barrow likely to weather very slowly?
Limestone in a barrow is likely to weather very slowly due to its dense and compact nature, which makes it less susceptible to physical and chemical weathering processes. Additionally, if the limestone is situated in a well-drained or stable environment, it minimizes the exposure to water and acids that can accelerate weathering. The presence of protective vegetation or soil cover can further shield the limestone from erosive elements, contributing to its slow weathering rate.
Why is limestone least resistant to weathering and erosion?
It is susceptible to chemical weathering more than other rocks from exposure to naturally acidic rainfall and groundwater.
Are limestone rocks least susceptible to weathering?
Limestone rocks are actually quite susceptible to weathering due to their composition of calcium carbonate. They can be easily eroded by rain, wind, and chemical reactions, leading to the formation of karst landscapes and caves over time.
What is a component of granite that is not susceptible to chemical weathering?
Quartz is a component of granite that is not susceptible to chemical weathering. Quartz is a very durable mineral that can resist the chemical breakdown caused by exposure to elements like water and air.
Minerals resistant to chemical weathering?
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.
Can limestone be worn away?

How reactive is limestone?
Limestone is a relatively non-reactive rock. It is generally resistant to chemical weathering, but can slowly dissolve in acidic solutions over time. This makes it susceptible to erosion when exposed to acidic environments.
Is limestone cave formation chemical or mechanical weathering?
chemical change
Which one is slow at weathering limestone or granite?
Limestone weathers faster than granite because it is more susceptible to chemical weathering due to its composition of calcium carbonate. Granite, on the other hand, is a more resistant rock as it is composed of harder minerals like quartz and feldspar.
Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Is limestone with holes mechanical or chemical weathering?
Limestone with holes is typically a result of chemical weathering. The holes are often created through the process of carbonation, where carbonic acid in rainwater reacts with the calcium carbonate in limestone to dissolve it and create cavities over time.
