Using the Earth's resources and obtaining potable water

Question

A. It requires less energy and reduces rock movement
B. It produces more waste rock
C. It is faster than traditional mining
D. It only extracts gold

Answer

The correct option is It requires less energy and reduces rock movement. This answer is correct because it matches the approved learning objective to compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only) in the subtopic Alternative methods of extracting metals.

Explanation

The correct option is It requires less energy and reduces rock movement. It requires less energy and reduces rock movement is correct because it directly supports the approved learning objective to compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only). This belongs to the subtopic Alternative methods of extracting metals within Using the Earth's resources and obtaining potable water, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Alternative methods of extracting metals.

Common mistake

Confusing Mining Methods

Students often confuse phytomining and bioleaching with traditional mining methods, thinking they are the same.

Do not treat this as a general statement about HT only. Instead, answer by clearly linking the correction to compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only) in Alternative methods of extracting metals. This keeps the response inside Using the Earth's resources and obtaining potable water and prevents a vague or off-topic GCSE answer. The mistake to avoid is: students often confuse phytomining and bioleaching with traditional mining methods, thinking they are the same.
