Learning objective

Students should be able to explain various techniques for extracting rocks and minerals from the Earth, including surface mining methods such as opencast, open-pit, open-cut, and strip mining, as well as subsurface mining techniques like deep and shaft mining. Additionally, they should discuss the factors influencing the choice to extract these resources, which include exploration, geology, accessibility, environmental impact assessments, and supply and demand.

Read the explanation, check the common trap, then practise with flashcards and questions.
