- Improving processes and products - OCR Gateway
  Most metals are extracted from ores. Iron and aluminium are extracted in different ways because they differ in reactivity. Life-cycle assessments analyse the environmental impact of products.
- Fuels - OCR Gateway
  Crude oil is a finite resource. Petrol and other fuels are produced from it by fractional distillation. These fuels are non-renewable resources. Cracking helps match supply of fractions with demand.
- The atmosphere - OCR Gateway
  Earth’s early atmosphere probably had less oxygen than now, but more carbon dioxide and water. Increases in greenhouse gases are leading to climate change.

- Radioactive emissions - OCR Gateway
  Unstable atomic nuclei emit radiation. Each type of radiation has different properties and interacts with matter in varying ways. Radioactive decay is random but can be measured. People are exposed to sources of radiation in all aspects of everyday life. Radioactive sources can be very useful but need handling carefully to ensure safety.
