Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Give three environmental problems associated with coal.

    Model answer

    Carbon dioxide emissions driving climate change, sulphur dioxide and particulates damaging air quality and health, and land disturbance from opencast mining.

  2. 2

    Explain how acid rain forms from fossil fuel combustion.

    Model answer

    Sulphur dioxide and nitrogen oxides released by burning dissolve in atmospheric moisture to form dilute acids, which fall as rain far downwind.

  3. 3

    Give two environmental problems associated with oil transport.

    Model answer

    Tanker spills contaminating coastlines and killing wildlife, and pipeline leaks polluting soil and groundwater.

  4. 4

    Give one environmental drawback of a large hydroelectric dam.

    Model answer

    The reservoir floods valley land and habitat, displaces communities, and traps sediment that would have maintained the floodplain and delta downstream.

  5. 5

    Give two environmental objections to wind farms.

    Model answer

    Visual and noise intrusion in valued landscapes, and collision risk to birds and bats.

  6. 6

    Give one environmental problem associated with nuclear power.

    Model answer

    Highly radioactive waste that remains hazardous for thousands of years and for which no permanent disposal site is yet operating in most countries.
