Test: Human Resources - 2 - Class 8 MCQ

The correct answer is C: The number of live births per 1,000 people.
- Birth rate refers to the number of live births per 1,000 people in a specified population.
- It is a crucial demographic indicator that helps in understanding the growth and dynamics of a population.
- By calculating the birth rate, we can assess the fertility level and make projections about future population trends.
- It is usually represented as the number of live births per 1,000 individuals in a given year.

The image implies a decrease in population.
- Therefore, the correct answer is B: Decrease in population.

- A population pyramid with a high birth rate and low death rate will have a wide base, indicating a large number of young people.
- The pyramid will not narrow rapidly towards the top because a low death rate implies more people are surviving to older ages.
- Therefore, the correct answer is B: "Not narrow rapidly towards the top," as the pyramid will have a fairly broad shape throughout, indicating a growing population with many young individuals.

The non-physical factor that affects population distribution in a country is "Stable Governments." Here's a concise breakdown:
- Stable Governments:
- Political stability influences where people choose to live.
- Countries with unstable governments often face population displacement and migration.
- Citizens seek areas with secure governance for safety, employment, and social services.
Stable governance fosters economic growth and social well-being, attracting and retaining populations within a country.

More than 90% of the world's population lives in about 30% of the land surface. The 10 most populous countries of the world contribute about 60 percent of the world’s population.

The correct answer is C: They are industrial belts providing large employment opportunities.
- In densely populated areas like Osaka and Mumbai, industries are major sources of employment.
- Industries attract a large workforce due to diverse job opportunities.
- The availability of jobs in these industrial belts is a key factor drawing people to settle in these areas.
- This influx of people seeking employment contributes to the dense population in these regions.

• The term life span is most commonly confused with another important concept: life expectancy.
• While both terms relate to the number of living years, they actually define very different concepts.
• While the term life span refers to the maximum number of years an individual can live, life expectancy refers to an estimate or an average number of years a person can expect to live. Most simply put, life expectancy can be attributed to and impacted by an individual and their personal health history, genetics, and lifestyle, whereas life span holds for all living humans.

as left side heavy means birth rate is more so population increases

The correct answer is B: Migration. Here's an explanation in detail:
- Migration: It refers to the movement of people into or out of an area. This movement can be within a country (internal migration) or between countries (international migration).
Migration plays a significant role in changing the demographics and socio-economic dynamics of both the origin and destination areas. It can affect population growth, cultural diversity, labor markets, and more. Understanding migration patterns is crucial for social scientists, policymakers, and urban planners.

Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy. Human factors that affect population density include social, political and economic factors.

Measure of the intensity of land use, expressed as number of people per square kilometer or square mile. Also called density of population.

Population density 

Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.

Population density tells you how crowded an area is, on average. It can help you figure out the resources that a certain area requires, and it can help you compare areas. You'll need to gather data about the area and population size, then plug the numbers into the population density formula: Population Density = Number of People / Land Area.

The correct answer is:
- A: The difference between the birth rate and the death rate of a country
Explanation:
- The natural growth rate is determined by subtracting the death rate from the birth rate in a specific population or country.
- It signifies the rate at which a population is growing or declining due to the difference between births and deaths.
- This rate does not take into account other factors like migration, making it a key indicator of population change based solely on births and deaths.

Area of land: 148 326 000 km2 (57 268 900 square miles), this are 30% of the total surface of Planet Earth. Area of water: 361 740 000 km2 (139 668 500 square miles), this are 71% of the total surface of the Earth. 97 percent is salt water and only 3 percent is fresh water.

Using resources carefully, judicially and giving them time to get renewed is called resource conservation. It is very necessary to use the resources very carefully as they are part of our life support system.

The correct option is D.
A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population.

• Population change specifically denotes the fluctuation in the total number of individuals residing within a defined region.
• It signifies variations in birth rates, death rates, migration patterns, and other demographic factors that impact the overall population size of a specific area over a given period.
• Monitoring population change is crucial for understanding societal dynamics, resource allocation, urban planning, and policymaking.

Alaska in North America is more populated due to the availability of mineral resources. Here's why:
- Mineral Resources: Alaska is rich in natural resources like oil, gas, gold, and other minerals, attracting people for employment and economic opportunities.
- Economic Prospects: The presence of these resources drives industrial development and job creation, enticing more residents.
- Economic Stability: The exploitation of mineral resources contributes to the state's economy, supporting infrastructure development and services.
- Population Growth: The promise of employment and economic stability due to these resources leads to a higher population in Alaska.
