Many of the Earth’s resources are finite. Chemists have a role in estimating the amount of reserves remaining and ensuring that the use of resources is sustainable.
Which of the following statements about the global population is true?
It is growing at a fast and increasing rate
It remains approximately constant
It is growing at a slow and steady rate
Which of the following is not a use for the Earth's resources?
Fuels for transport
What name is given to resources which may run out one day if not managed carefully?
Which of these is a finite resource?
Before 1910, where did the majority of fertilisers come from?
What name is given to the method by which nitrogen from the air is turned into ammonia?
The Haber process
The contact process
The Kroll process
Which process is used to turn crude oil into useful liquids, each of which has a narrow range of boiling points?
What term can be used to describe the relationship between two factors when they have the same trend over time, such as increasing global population and global copper production?
Why did the development of the Haber process allow the global population to increase?
Synthetic fertilisers were easier to obtain with less transport needed
Synthetic fertilisers allowed intensive farming, producing more food
Fertilisers became much more expensive than before
Why is it essential that the humans alive on Earth today do not use up all of the Earth's resources?
So that future generations of humans can meet their own needs
To encourage the exploration of resources on other planets using new technology
To provide an incentive to the chemical industries to innovate and make new chemicals
