Renewable and Non-Renewable Resources Quiz

Question 1An illustrative deposit has reserves of 840 tonnes and annual production of 35 tonnes. Define its reserves-to-production ratio as reserves divided by yearly production. Find the ratio in years, rounded to two decimals.

Enter a number in years.

Answers within 0.005 years of the expected value are accepted.

Question 2A system supplies 240 MWh of electricity, including 84 MWh from wind. Find wind’s share as a percentage, rounded to two decimals.

Enter a number in %.

Answers within 0.005 % of the expected value are accepted.

Question 3Timber is harvested faster than the woodland regrows. Which assessment fits the resource?

A non-renewable deposit created by geological accumulationA stable stock maintained by the renewable classificationAn expanding stock because harvesting restarts tree growthA renewable stock being drawn down by excessive use

Question 4An aquifer receives negligible recharge on human timescales. What matters when classifying its usable water?

The general fact that rain falls somewhere on EarthThe number of pumps installed above the aquiferThe local replenishment rate compared with withdrawalThe renewable label assigned to water without regard to location

Question 5Used metal is recovered and remade into components. How does this affect its resource category?

It converts the mineral into a biologically renewing resourceIt conserves a finite mineral stock through recyclingIt recreates the original ore deposit undergroundIt demonstrates that recovery has no processing losses

Question 6A fuel is burned, while a metal component is recovered for reuse. What distinction matters?

Both materials return to their original deposits after useBurned fuel retains its original chemical form for repeated burningRecovering metal creates the energy released by burning the fuelBurning transforms the energy source unlike recovering useful atoms

Question 7A proposed generating project is called renewable. What else belongs in evaluating its environmental effects?

Renewable status establishes negligible construction damageEquipment and land use contribute impacts throughout the system’s lifeElectricity generation places waste disposal outside the assessmentAvoiding fuel purchases establishes an absence of habitat disturbance

Question 8A solar installation has a rated capacity but operates under changing daylight. What determines the energy it supplies?

Actual power summed over time with changes in sunlight accounted forAnnual energy equal to the installation’s rated powerPanel count used to calculate annual energy without output ratingsPeak output sustained through the hours of darkness

Question 9A manufacturer substitutes a different material for a scarce mineral. What must the comparison consider?

Performance and sourcing impacts as tests of the proposed substitutionThe performance improvement delivered by a change in material nameThe replacement’s freedom from resource costs after mineral use endsOriginal deposit size as the test of the replacement’s performance

Question 10Recycling expands while demand for a metal grows rapidly. Why might mining continue?

Recycled metal is unsuitable for manufacturing durable productsRecycling lowers extraction costs rather than supplying recovered metalRecovery losses and expanding stocks leave demand for new materialA growing recycled share means the amount of mined metal has fallen
