- 1. What is a finite resource? (also called non- renewable resources) A resource that will eventually run out like coal What is a renewable resource? A resource that won’t run out or can be easily replaced like wood What is potable water? Water that is safe to drink (it can contain dissolved substances so doesn’t have to be pure water) State the sterilising agents use to make water potable in the UK Chlorine, ozone or ultraviolet light What is desalination? The process of removing salt from seawater Describe the process of distillation Water is heated until it evaporates leaving behind any salt or other substances that are dissolved in it. It is the condensed to obtain pure liquid water Describe the process of reverse osmosis Seawater is pushed through a semi-permeable membrane which allows the water molecules through but not the salt molecules State the stages in waste water treatment • screening and grit removal • sedimentation to produce sewage sludge and effluent • anaerobic digestion of sewage sludge • aerobic biological treatment of effluent. HT ONLY – Describe phytomining The use of plants to absorb metal compounds. The plants are harvested and then burned to produce ash that contains metal compounds. HY ONLY – Describe bioleaching Bioleaching uses bacteria to produce leachate solutions that contain metal compounds What is a life cycle assessment (LCA)? An assessment of the environmental impact of products in each stage of its production, use and disposal Key Facts Memory Task: Using Resources
