C14 - Earth's resources
Independent learning
Introduction
All of the resources we use in our everyday lives come from the atmosphere or the Earth's crust. Most of these resources are finite and we have used up most of the accessable sources. In this unit we will look at how we extract useful materials from the rocks beneath our feet, how we can make drinking water and deal with the waste we produce.

Markscheme
resources
(recycling) conserves supplies of ores
copper available for longer
as (at present rate of use) copper ores will run out in about 35 years
(recycling) conserves supplies of fossil fuels or energy
less fuel used at a lower cost
land pollution
mining scars landscape or produces noise pollution
mining destroys wildlife habitats
(recycling) less need to mine ores / fossil fuels
so less habitat destroyed or less scarring of landscape
(recycling) less need to use landfill for waste
atmospheric pollution
burning fossil fuels produces carbon dioxide / greenhouse gas
which (may) cause global warming or climate change
extraction produces sulfur dioxide
which causes acid rain
which can kill trees / fish
Task 6: Life cycle assessment
Task 6b: Make notes that:
Define Life cycle assessment
List the stages involved in a life cycle assessment
Describe the problems associated with life cycle assessments
Answer the questions
self mark using slide 15.
