What is an example of natural resource used for fuel? Oil
What types of products can these natural resources be replaced by? Some of these natural products can be replaced by synthetic products or improved upon by man-made processes.
What provides conditions where natural resources can be enhanced for our needs? Give an example. Agriculture provides conditions where natural resources can be enhanced for our needs. E.g. the development of fertilisers have meant we can produce a high yield of crops.
What will happen to some natural resources in the future? Some natural resources will run out.
What is the benefit of renewable resources? Renewable resources reform at a similar rate to, or faster than, we use them.
Give 3 examples of renewable resources. Timber is a renewable resource as trees can be planted following a harvest and only take a few years to regrow. Other examples of renewable resources include fresh water and food.

What happens to finite resources after they've been extracted? After they've been extracted, many finite resources undergo man-made processes to provide fuels and materials necessary for modern life.
What is fractional distillation used for? Fractional distillation is used to produce usable products such as petrol from crude oil and metal ores are reduced to produce a pure metal.
What is the downside of extracting finite resources? Extracting finite resources has risks.
What are many modern materials made from? Give 3 examples. Many modern materials are made from raw, finite resources, for example most plastics, metals and building materials.
what 3 effects do people have to balance when extracting finite resources? People have to balance the social, economic and environmental effects of extracting finite resources.
