AQA A-Level Environmental Science 3.3 Energy resources overview quiz quiz

Land plants buried in swamps

Marine microorganisms in seabed sediments

Volcanic ash deposits

Dissolved minerals in groundwater

They are only ever found in a small number of countries around the world

They form far more slowly than they are used

They cannot be transported very easily over long distances

They release carbon dioxide when they are burned

Carbon dioxide

Water vapour

Sulfur dioxide

Argon

To produce electricity directly from the fission reaction itself

To enrich the uranium fuel to a higher grade

To absorb the excess neutrons released

To boil water and produce steam that drives turbines

It produces radioactive waste that stays hazardous for thousands of years

It produces very large amounts of carbon dioxide during its normal operation

It depends entirely on the weather and the time of day

It has a very low energy output for its size

Geothermal and tidal

Solar and wind

Hydroelectric and geothermal

Tidal and wave

They release large amounts of sulfur dioxide

They depend on sunshine

They flood land and disrupt river ecosystems

They produce radioactive waste

It is burned at very high temperatures in a sealed furnace each time

It is mixed with coal before being burned

It is stored deep underground after harvest

The crops or trees are replanted to reabsorb the carbon released

Getting the same useful output from less energy input

Using less energy overall by changing your behaviour

Generating energy from renewable sources only, never from fossil fuels

Storing surplus energy in large batteries

Leaving the lights switched on in empty rooms

Installing loft and wall insulation

Raising the thermostat to a higher temperature

Using older, less efficient household appliances

Because it requires building expensive new power stations first

Because it actually increases overall fossil fuel use

Because the cleanest energy is the energy not used

Because it only ever works in heavy industry

Solar photovoltaic power

Onshore wind power

Offshore wave power

Geothermal power
