Answer:

Explanation:

Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn't have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn't require more expensive features like ventilation, communications, etc.
