Metals and other useful resources can be extracted from the Earth's crust. Life cycle assessments measure the environmental impact of a product over its entire life. Recycling helps to conserve energy and resources.
Which metal is found uncombined in the Earth's crust?
Which element removes oxygen from iron(III) oxide in the industrial extraction of iron?
What is the first stage in a life-cycle assessment (LCA)?
Using the product during its lifetime
Extracting and processing the raw materials
Disposing of the product at the end of its lifetime
Which of the following is not part of a life-cycle assessment (LCA)?
Manufacturing the product and packaging
Advertising and marketing the product
Which of the following is an environmental consideration when evaluating the manufacturing of a product?
Energy used by the manufacturing process
Wages paid to the workers on the production line
The cost of the equipment needed for manufacturing
Which of the following will have the greatest impact on the environment during its lifetime of use?
A plastic garden table and chairs
A wooden garden table and chairs
Which of the following has the least damaging effect on the environment at the end of a product's life?
Which of the following is a disadvantage of recycling copper?
It has an incredibly high melting point
Copper reacts quickly with oxygen so it is difficult to obtain pure copper through recycling
It can be difficult to separate different metals
Which of the following organisms cannot be used to obtain copper from low-grade ores? - Higher
What factor does the biological extraction of copper, using phytoextraction, depend on? - Higher
That copper compounds are poisonous
That plants can take in copper compounds from the soil
That photosynthesis stores energy in plants
