What are the advantages and disadvantages of mining and quarrying?
disadvantages of mining is that the chemicals used to extract the minerals will go down lakes which well put a big impact on the environment
This answer needs a slight correction. Chemicals are NOT used to extract minerals during mining in the United States. In some instances in South America, chemicals are used to "cluster" ores together, but this practice is not used in the United States. "Pollution of streams" that occurs in the United States is usually from the natural acidity of the geologic formations. Mining companies in the United States are required by federal law to take steps to decrease the drainage of acidic strata, so water pollution is not as prevalent as believed.
for this question you simply need to say what mining is and what quarrying is. here is how you write the answer: Mining is the extraction of metals from their ore and quarrying is the digging up for limestone, the resemble of limestone quarrying and mining metals both include digging up minerals from earth. this question normally worth 2 or 3 marks. hope i helped :)
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining. * It is also faster The disadvantages of surface mining are: * That it destroys the landscape and environment * Effects the habitats of fauna potentially effecting the existing ecosystem in that area * Flora is destroyed * Causes noise…
