Mark scheme
Marking points from the official mark scheme. The mark or mark type is shown in brackets.
- Question 22 (a) Marks will be awarded for describing the pattern of global energy consumption. One mark for each valid point. E.g. Fossil fuels (coal, oil, gas) account for the majority of global energy consumption (1) with oil being the most consumed fossil fuel (1). Renewable energy sources make up the smallest proportion (1). (3)
- Question 22 (b) Marks will be awarded for two appropriate environmental impacts. One mark for identifying the impact and one for the explanation. E.g. Burning fossil fuels releases greenhouse gases (1) which contribute to global warming and climate change (1). Acid rain can occur (1) as gases like sulfur dioxide are released from burning fossil fuels (1). (4)
