World Population Explosion! Trivia Quiz
In human population studies, the rapid increase in the number of humans occupying a geographical location at a particular time is referred to as human population explosion. It poses a threat to ecological sustainability and remain one of the problems with which the United Nations is concerned. How much do you know about this? Take this quiz if you are in the know!

What is the most direct cause of population explosion?
- A.
Increase in births
- B.
Better national economy
- C.
Increase in disposable income
- D.
Increase in employment rate
Correct Answer
A. Increase in birthsExplanation
The most direct cause of population explosion is an increase in births. When the birth rate exceeds the death rate, the population grows rapidly. This can be due to various factors such as improved healthcare, better access to education, cultural beliefs, and social norms. When couples have more children and the overall fertility rate increases, it leads to a population explosion.Rate this question:

What is the most direct cause of reduction in human population?
- A.
Decrease in disposable income
- B.
Famine
- C.
Increase in mortality rate
- D.
Increased incidence of natural disasters
Correct Answer
C. Increase in mortality rateExplanation
Increase in mortality rate is the most direct cause of reduction in human population. When the mortality rate increases, more people die, leading to a decrease in the overall population. This can be caused by various factors such as diseases, epidemics, wars, or other catastrophic events that result in a higher number of deaths. As mortality rate rises, it directly affects the population size by reducing the number of individuals alive.Rate this question:

Which of these does not increase human population?
- A.
Increase in mortality rate
- B.
Increase in natality rate
- C.
Increase in immigration
- D.
Increase in disposable income
Correct Answer
A. Increase in mortality rateExplanation
Increase in mortality rate does not increase human population because it refers to the number of deaths within a population. When mortality rate increases, it means more people are dying, which reduces the overall population size.Rate this question:

Which of these does not lead to the decrease in human population?
- A.
Increase in immigration
- B.
Decrease in immigration
- C.
Decease in mortality rate
- D.
Increase in birth rate
Correct Answer
A. Increase in immigrationExplanation
Increase in immigration does not lead to a decrease in human population because immigration refers to the movement of people into a country or region, which actually increases the population. When more people immigrate to a certain area, the population of that area increases rather than decreases.Rate this question:

Which of these is most likely to cause population explosion in natural disaster prone areas?
- A.
Decrease in incidence of natural disaster
- B.
Increase in incidence of natural disaster
- C.
Increase in quality of life
- D.
Decrease in quality of life
Correct Answer
B. Increase in incidence of natural disasterExplanation
An increase in the incidence of natural disasters is most likely to cause population explosion in natural disaster prone areas. When there is a higher frequency or intensity of natural disasters such as hurricanes, earthquakes, or floods, it can lead to displacement of people from their homes and encourage population growth in safer areas. This can result in overcrowding and strain on resources in the disaster-prone areas, leading to a population explosion.Rate this question:

What does the carrying capacity of a location occupied by a group of people means?
- A.
Resources
- B.
Natural disaster
- C.
Disposable income
- D.
Power
Correct Answer
A. ResourcesExplanation
The carrying capacity of a location occupied by a group of people refers to the maximum number of individuals that the location can sustainably support based on the available resources. It indicates the limit to which the population can grow without depleting or overusing the resources of the area. This concept is important in understanding the balance between human population and the environment, as exceeding the carrying capacity can lead to resource scarcity, environmental degradation, and a decline in quality of life.Rate this question:

Which of these vegetation types does not favour population explosion?
- A.
Savannah vegetation
- B.
Rain forest vegetation
- C.
Woodland
- D.
Desert
Correct Answer
D. DesertExplanation
Desert vegetation does not favor population explosion because it is characterized by extreme aridity and limited water availability. The lack of water and harsh environmental conditions make it difficult for plants and animals to survive and reproduce in deserts. As a result, the population density in desert regions is generally low compared to other vegetation types, making it unfavorable for population explosion.Rate this question:

Which of these forms of revolution does cause population explosion?
- A.
Industrial revolution
- B.
Agricultural revolution
- C.
Industrrial revolution
- D.
Technological revolution
Correct Answer
A. Industrial revolutionExplanation
The correct answer is Industrial revolution. The Industrial revolution, which began in the 18th century, brought about significant advancements in technology, manufacturing, and transportation. These advancements led to increased productivity and improved living conditions, which in turn resulted in a population explosion. The availability of new machinery and the expansion of industries created job opportunities and improved standards of living, leading to a rapid increase in population.Rate this question:

Which of these is a medical invention against population explosion?
- A.
Contraception
- B.
Agriculture
- C.
Urbanization
- D.
Education
Correct Answer
A. ContraceptionExplanation
Contraception is a medical invention that helps control population growth by preventing unwanted pregnancies. It allows individuals to make informed choices about their reproductive health and family planning. By providing access to contraception, the rate of unplanned pregnancies can be reduced, thereby helping to address the issue of population explosion. Agriculture, urbanization, and education, while important in their own ways, are not specifically medical inventions targeted at population control.Rate this question:

What is the leading cause of population explosion in Asia?
- A.
Decrease in mortality
- B.
Improvement in economy
- C.
Political stability
- D.
Friendly immigration policy
Correct Answer
A. Decrease in mortalityExplanation
The leading cause of population explosion in Asia is the decrease in mortality. This means that there has been a significant reduction in the number of deaths in the region, resulting in a higher number of people surviving and living longer. This decrease in mortality can be attributed to advancements in healthcare, improved access to medical facilities, better sanitation, and overall improvements in living conditions. As a result, the population in Asia has been rapidly increasing, leading to a population explosion.Rate this question:
