IGCSE Geo: Over- and Under-Population

What is over-population?

• When the use of resources by the population is greater than the resources available

• When the use of resources by the population is lower than the resources available

• When the population is stable

• When the population is at an optimum level

What are some issues associated with over-population?

• Low levels of production and exports

• Insufficient population to defend a country from aggressive countries

• Increased levels of pollution

• Fewer customers for services

What is under-population?

• When the use of resources by the population is greater than the resources available

• When the use of resources by the population is lower than the resources available

• When the population is stable

• When the population is at an optimum level

What are some issues associated with under-population?

• Low levels of production and exports

• Fewer customers for services

• Insufficient population to defend a country from aggressive countries

• Increased levels of pollution

What is carrying capacity?

• The number of people that an area’s resources and technology can decrease

• The number of people that an area’s resources and technology cannot support

• The number of people that an area’s resources and technology can support

• The number of people that an area’s resources and technology can increase

What can lead to a decrease in the carrying capacity of a region?

• Discovery of new gas or oil reserves

• Agricultural and industrial revolutions

• Natural events such as drought

• Increasing consumption and pollution

What is one of the main risks surrounding the Earth’s natural resources?

• Fluctuating consumption and pollution due to the rapidly increasing population

• Increasing consumption and pollution due to the rapidly increasing population

• Decreasing consumption and pollution due to the rapidly increasing population

• Stable consumption and pollution due to the rapidly increasing population

What does the Earth not have the carrying capacity to sustain?

• Fluctuating level of population growth

• Stable level of population growth

• Decreasing level of population growth

• Current level of population growth

What may help some regions adapt their carrying capacity to sustain the population at an optimum level?

• Over development and increasing rates of consumption

• Well-planned developments and reducing consumption

• Stable development and consumption

• Fluctuating development and consumption

What is the impact of under-population on a country's economy?

• Low levels of production and exports

• High levels of production and exports

• Stable levels of production and exports

• Fluctuating levels of production and exports
