4.[2]
Outline one strength and one limitation of the demographic transition model.
5.[3]
Outline the socioeconomic factors that may cause a society to move from Stage 2 to Stage 3 on the demographic transition model.
Question 4
HLPaper 2
1.[5]
Describe three principles of a circular economy as they apply to solid waste management.
Question 5
SLPaper 2
1.[4]
Outline four ways urbanization may influence processes in the hydrological cycle.
2.[7]

Question 6
HLPaper 2
1.[6]
Discuss the advantages and disadvantages of incineration as a solid waste disposal option.
Question 7
SLPaper 2
1.[4]
Using named examples, distinguish between the concept of a “charismatic” (flagship) species and a keystone species.
2.[7]
Explain the role of two historical influences who shaped the development of the environmental movement.
3.[9]
Discuss the role of environmental value systems in the protection of tropical biomes.
Question 8
SLPaper 2
1.[4]
Explain the processes involved in the formation of fertile soils from bare rock.
2.[7]
Discuss how negative and positive feedback mechanisms may influence the growth of decomposer populations in the soil.
3.[9]
To what extent are natural limiting factors more likely than population policies to limit global human population growth in the future?
Question 9
HLPaper 2
1.[4]
Explain the role of Environmental Impact Assessments (EIAs) in sustainable resource management.

2.[2]
The soil system includes storages of inorganic nutrients.
Identify two outputs from these storages.
3.[7]
Solid domestic waste may contain non-biodegradable material and toxins that have the potential to reduce the fertility of soils.
Explain how strategies for the management of this waste may help to preserve soil fertility.
4.[9]
The provision of food resources and assimilation of wastes are two key factors of the environment that determine its carrying capacity for a given species.
To what extent does the human production of food and waste each influence the carrying capacity for human populations?
