A flat layer of phosphates is found in sedimentary rock just beneath Earth’s surface. Which type of mining would be best for this type of resource?

• Strip mining

• Hydraulic mining

• Block cave mining

• Evaporative Mining

Why does the use of fossil fuels present a major global challenge?

• The gases they release when burned are difficult to track, and the power they provide is inconsistent.

• They are technically a nonrenewable resource, but at the rate we are using them, they can be considered renewable.

• The pollution they cause must be balanced with their abundance and relatively cheap costs when their hidden costs are not accounted for.

• The removal of fossil fuels from the ground has been shown to significantly alter the degree of Earth’s tilt resulting in a change of climate.
