A power plant burns coal formed from swamp plants buried over millions of years. How is that fuel classified?

Solar panels use sunlight that arrives daily from the Sun. How is sunlight classified as a resource?

A mine removes copper ore from a finite deposit in Earth's crust. What kind of resource is the copper ore?

A managed forest is replanted and harvested no faster than trees regrow. How is timber classified?

Natural gas forms underground from ancient organisms and can be used much faster than it forms. How is it classified?

Wind turns turbines as moving air passes through a region. In resource terms, wind is best classified as what?

A country has steep mountains, heavy rainfall, and fast rivers. What energy source best matches that physical setting?

An island has narrow bays and a very large difference between high and low tide. What energy source fits that coastline?

A region sits on an active plate boundary with hot springs and volcanoes. What domestic energy source is most likely there?

A dry plateau has clear skies most of the year and intense sunlight. What energy source is best suited to that environment?

A broad plain and nearby mountain passes have steady prevailing winds. What electricity source fits this setting?

A farming region has crop waste and animal manure available for local heat and electricity. What energy source uses that material?

A fishery harvests fewer fish each year than the stock replaces through reproduction. What does that practice protect?

A forest cuts only the volume of wood that regrows each year. What resource condition does this sustainable rate protect?

A town pumps groundwater at a rate lower than the aquifer's yearly recharge. What does this protect?

A ranch keeps grazing below the grassland's carrying capacity so plants regrow. What is protected?

A river district caps how much water farms may divert, so a set minimum flow always stays in the channel. What does that rule protect?

Farmers keep soil erosion below the rate at which new soil forms. What resource does that protect?

A country has no oil fields and buys nearly all the fuel it burns from abroad. What is its economy exposed to?

A country generates most electricity from imported natural gas, and a pipeline abroad can be closed. What risk does this create?

An island imports coal for power plants, and shipping routes become more expensive. What vulnerability does this show?

A landlocked country relies on diesel brought through a neighbor's port and roads. What does this dependence expose it to?

A country pays for most imported energy in dollars; global prices rise while its currency weakens. What is the likely exposure?

Factories depend on rare earth minerals imported from one supplier, which restricts exports. What is the economy exposed to?

An open-pit mine removes vegetation and topsoil from a hillside before ore is taken out. What is likely to increase there?

A timber company clears trees and scrapes soil to build haul roads on steep slopes. What physical process is likely to increase?

Strip mining removes surface layers over a coal seam, leaving loose spoil piles exposed to rain. What often follows?

Drilling pads and access roads remove desert plants and crust from dry soil. What ground impact is likely?

A limestone quarry strips soil and breaks rock on a bare site before heavy rain. What land-surface effect is likely?

Oil-sands surface mining clears boreal forest and peat before bitumen is removed. What immediate land impact does this cause?
