Test: Population - The Increasing Numbers and Rising Problems - Class 10 MCQ

Unchecked population growth leads to decreasing land availability as more land is used for cultivation, housing, and industry. This reduction in usable land poses significant challenges for food production and environmental sustainability.

Vasectomy is a surgical procedure performed on men to prevent pregnancy by ligating the vas deferens, thereby preventing sperm from being released during ejaculation. It is considered a permanent form of contraception.

Controlled population growth aims to achieve a balance between human needs and the availability of natural resources. It emphasizes the importance of sustainability and the need to manage population size to prevent resource depletion and environmental harm.

The Industrial Revolution was a turning point in human population growth as it led to increased job opportunities and improved food production. This period allowed more people to thrive and contributed to a significant rise in the world population.

Urbanization leads to the overuse of natural resources as cities expand and more people rely on these resources for their daily needs. This can result in pollution and depletion of resources.

The growth rate of a population is determined by the difference between the birth rate and the death rate. If the birth rate exceeds the death rate, the population grows, and vice versa.

Decreased birth rates do not contribute to rapid population growth; instead, they would lead to a slowdown in population increase. Enhanced healthcare, nutrition, and immunization are key factors that support higher birth rates and population growth.

The diaphragm is a barrier method of contraception that prevents sperm from entering the uterus during sexual intercourse. It is designed to be inserted into the vagina before intercourse.

Rapid population growth increases the burden on healthcare systems, making it challenging to provide adequate services and resources. This can lead to overworked medical professionals and diminished quality of care.

Population density refers to the measurement of the number of individuals living per square kilometer at a specific point in time. This metric helps understand how crowded an area is and informs urban planning and resource management.

Demography is defined as the statistical study of human populations, focusing on aspects such as size, density, distribution, and other vital statistics. This field helps policymakers understand population trends and dynamics.

Major breakthroughs in medical science, particularly the development of antibiotics and vaccines, played a crucial role in reducing mortality rates, thereby contributing to rapid population growth.

The death rate, or mortality rate, is defined as the number of deaths occurring in a population per 1,000 individuals per year. This statistic is crucial for understanding population health and dynamics.

Reducing the rate of population growth can lead to improved educational opportunities for children, as fewer students in schools allows for more personalized attention and resources, ultimately enhancing educational outcomes.

High infant mortality rates result in more pregnancies as families often have more children to ensure some survive to adulthood. This is a significant factor in the population explosion experienced in India.

Wavy gaps represent long periods of stability in population growth or very slow rises. These patterns indicate that the population is not experiencing significant changes during these intervals.

Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. This approach encourages responsible resource use and environmental protection.

The current birth rate is more than 100,000 babies born each day, highlighting the ongoing rapid increase in the global population and the challenges it presents for resources.

The three key aspects of family welfare are Family Planning, which emphasizes small families; Total Welfare, ensuring the well-being of families; and Child Care, focusing on the health and nutrition of children and mothers.

World Population Day is observed to raise awareness of population issues, including the challenges of rapid growth and the importance of family planning and sustainable development.
