Methods of Rock Extraction

There are 3 different methods of exploiting rock from the earth. One is Drilling. This is when Fossil

fuels such as oil and gas are extracted from underground reservoirs by drilling down into the ground

and pumping them to the surface. If oil or gas is found under the sea,

drilling takes place from an offshore platform or rig. The oil or gas is then pumped ashore

through a pipeline. This is called offshore drilling, as occurs at the Corrib Gas Field

.2. Opencast mining/quarrying. This is when If a resource is on or near the surface

of the Earth, opencast mining is used to extract it. This is the cheapest

form of mining, but it is very noisy and dusty, and can scar the landscape.
