NGS Population Dynamics Sec 2: Human Population

Front

What is demography?

Back

The study of human populations

Answer explanation

Demography is specifically the study of human populations, including their size, distribution, and trends. The other options focus on marine life, animals, and plants, which are not related to demography.

Front

What does it mean when a population is experiencing rapid growth?

Back

A large portion of the population is children

Answer explanation

Rapid population growth often indicates a high birth rate, typically due to a large portion of the population being children. This leads to more births than deaths, driving the overall growth.

Front

Which factor is NOT used to determine human population growth patterns? Age structure, Death rate, Weather patterns, Birth rate

Back

Weather patterns

Answer explanation

Weather patterns do not directly influence human population growth patterns. In contrast, age structure, death rate, and birth rate are key demographic factors that determine how populations grow or decline.

Front

How did agriculture affect human population growth?

Back

It increased the population

Answer explanation

Agriculture provided a stable food supply, which supported larger populations. This led to increased human population growth as communities could sustain more people compared to hunter-gatherer societies.

Front

What was a significant impact of the industrial revolution on the environment?

Back

It caused pollution of water, air, and soil

Answer explanation

The industrial revolution significantly impacted the environment by causing pollution of water, air, and soil due to increased industrial activities and urbanization, leading to detrimental effects on ecosystems and public health.

Front

What happens when there are more adults than children in a population?

Back

The population declines

Answer explanation

When there are more adults than children, the birth rate typically decreases, leading to fewer new individuals entering the population. This can result in a decline in the overall population over time.

Front

What is the effect of people moving to the suburbs?

Back

It causes stress on plant and animal habitats

Answer explanation

Moving to the suburbs often leads to urban sprawl, which can encroach on natural habitats, causing stress to plant and animal populations. This makes 'It causes stress on plant and animal habitats' the correct choice.

Front

The increase in population size has directly affected the environment by:

Back

Increasing demand for resources

Answer explanation

The increase in population size leads to higher demand for resources such as food, water, and energy, which can strain the environment. This choice accurately reflects the direct impact of population growth on resource consumption.

Front

Increasing population size has led to increased resource production and use, which has negatively impacted the environment. True or False?

Back

True

Answer explanation

True. An increasing population demands more resources, leading to overproduction and consumption, which harms the environment through pollution, habitat destruction, and depletion of natural resources.

Front

Which source changes the environment the least? Options: farming, a librarian putting away books, a factory, a bake sale, a car wash

Back

a librarian putting away books

Answer explanation

Source J, a librarian putting away books, changes the environment the least as it involves minimal physical alteration to surroundings compared to farming, factories, bake sales, or car washes, which all have greater environmental impacts.
