Which type of rock appear to be the least resistant to weathering and erosion?
Carbonate rocks, such as limestone, tend to be the least resistant to weathering and erosion.
Chemical weathering would be most effective in what condition area?
Environments with large amounts of rainfall and carbonate rock.
Are limestone rocks least susceptible to weathering?
No! Limestone is composed of significant amounts of calcite (calcium carbonate - CaCO3) which is soluble and so is relatively easy to weather.
Limestone weathering does not remove carbon di oxide from the atomospher.why not?
Limestone is made of Calcium Carbonate and is therefore a source of atmospheric Carbon dioxide when it weathers. CaCO3 -> CaO + CO2
How does underground water cause chemical weathering of limestone?
Rainfall that seeps through cracks in the bedrock is slightly acidic. The acid reacts with the calcium carbonate in the limestone, causing dissolution of the rock.
Which type of rock appear to be the least resistant to weathering and erosion?
Carbonate rocks, such as limestone, tend to be the least resistant to weathering and erosion.
What chemical weathering process is responsible for cave formation?
In most caves this process is the dissolution of calcium carbonate.
What is an example of chemical weathering affecting the rocks?
Rainwater is slightly acidic and will react with the calcium carbonate found in limestone and other rocks. The resultant erosion is an example of chemical weathering.
Chemical weathering would be most effective in what condition area?
Environments with large amounts of rainfall and carbonate rock.
How do people contribute to weathering of rocks?
We excavate them for many uses, we produce acid rain that erodes carbonate rocks, and we cut down forests, exposing rocks to weathering from rain and increased runoff.
Does Water and carbonic acid play a major role in the chemical weathering of rocks?
Yes, it is correct; for example calcium carbonate react with carbonic acid.
What do both weathering and erosion produce?
New rocks, landforms and structures. The first from the sediments from the weathered rocks. Also solutions of minerals such as calcium carbonate, from limestone.
Are limestone rocks least susceptible to weathering?
No! Limestone is composed of significant amounts of calcite (calcium carbonate - CaCO3) which is soluble and so is relatively easy to weather.
What roles does water play in cave formation?
Chemical weathering, esp. in carbonate rocks, aided to some extent as the conduit develops by mechanical erosion by the stream.
Limestone weathering does not remove carbon di oxide from the atomospher.why not?
Limestone is made of Calcium Carbonate and is therefore a source of atmospheric Carbon dioxide when it weathers. CaCO3 -> CaO + CO2
What does a cave have to do with chemical weathering?
Their existence! Almost all caves are in limestone, and formed by dissolution along joints of the rock's calcium-carbonate by rainwater acidified by atmospheric carbon dioxide.
Does acid rain cause potholes?
YES, acid rain can effect roads, highways and even bridges (if it is made out of calcium carbonate) it is formed by the freeze-thaw weathering. by MK
