Population Density And Population Distribution Quiz

Explanation
Antarctica is largely uninhabited due to its harsh climate. The continent experiences extremely low temperatures, strong winds, and long periods of darkness, making it inhospitable for human settlement. The extreme weather conditions make it difficult for people to survive, let alone establish permanent communities. Consequently, the harsh climate is the primary reason why Antarctica remains largely uninhabited.

Explanation
The number of children that a woman is expected to bear in her life is known as the fertility rate. This rate is often used as an indicator of population growth and demographic trends. It helps in understanding the reproductive patterns of a population and can be influenced by various factors such as access to healthcare, education, cultural norms, and economic conditions.

Explanation
When the birth rate increases, it means that more babies are being born. This leads to a faster rate of population growth because there are more individuals being added to the population. Therefore, the statement is true.

Explanation
When the death rate increases, it means that more people are dying within a given period of time. This leads to a decrease in the overall population size, as more individuals are being lost compared to the number of new individuals being born. As a result, the population growth rate slows down or even becomes negative if the death rate surpasses the birth rate. Therefore, the statement that death rate increases will cause a slow pace of population growth is true.

Explanation
The statement suggests that an increase in life expectancy from 65 to 75 will result in a slow pace in the rate of population growth. However, this is not necessarily true. While an increase in life expectancy may lead to a slower growth rate in some cases, it is not the sole determining factor. Other factors such as birth rates, death rates, and migration also play a significant role in population growth. Therefore, the statement is false as it oversimplifies the relationship between life expectancy and population growth.

Explanation
A huge decrease in infant mortality does not necessarily cause the population to decrease. While a decrease in infant mortality may lead to a decrease in the number of deaths among infants, it does not directly impact the birth rate or the overall population size. Other factors such as fertility rates, migration, and life expectancy also play a significant role in determining population changes. Therefore, the statement is false.

Explanation
A population pyramid with a wide base actually signifies that the population is increasing. This is because a wide base indicates a large number of young individuals in the population, which suggests a high birth rate and a growing population. On the other hand, a narrow base would indicate a smaller number of young individuals and a declining population. Therefore, the statement that a wide base signifies a decreasing population is incorrect.

Explanation
Relief refers to the physical features of the land, such as mountains, valleys, and plateaus. In the case of Dominica, which is a mountainous island in the Caribbean, relief has the greatest impact on the population distribution. The rugged terrain makes it difficult to build infrastructure and access certain areas, influencing where people choose to live. It also affects the availability of resources and economic activities, as certain areas may be more suitable for agriculture or tourism. Therefore, relief plays a significant role in shaping the population distribution in Dominica.

Explanation
The correct answer is near the coast. This is because coastal areas tend to have more favorable living conditions, such as access to resources, transportation, and economic opportunities. Additionally, living near the coast provides easier access to fishing and trade routes, which are important for the livelihood of the population.

Explanation
The highest population densities in Dominica are found in and around Roseau.

Explanation
The rate of Jamaica's population growth has been decreasing in the recent decade. This means that the population growth has been slowing down over time.

Explanation
In recent decades, Jamaica's fertility rate and birth rate have decreased. This means that fewer children are being born per woman and overall population growth is slowing down. This can be attributed to various factors such as increased access to education and healthcare, urbanization, and changing societal norms. The decrease in fertility and birth rates has significant implications for the country's demographic composition, social welfare, and economic development.

Explanation
The statement suggests that there is a higher number of people leaving Jamaica (emigration) compared to the number of people coming into Jamaica (immigration). However, the correct answer is False, indicating that immigration is not way more than emigration in Jamaica. This implies that there may be more people entering Jamaica than leaving, or the numbers may be relatively balanced.

Explanation
The given statement is "The population of the USA grows at a very slow pace." The correct answer is False. This means that the statement is not true. The population of the USA does not grow at a very slow pace. This could be due to various factors such as immigration, birth rates, and other demographic factors. The actual growth rate of the USA population may vary over time, but it is not considered to be slow.

Explanation
The explanation for the given answer "True" is that immigration is indeed a significant factor contributing to the population growth in the US. The country has a long history of attracting immigrants from various parts of the world, which has resulted in a steady increase in its population over the years. Immigration not only adds to the overall population numbers but also brings in cultural diversity and contributes to the country's economy and workforce. Therefore, it can be concluded that immigration plays a crucial role in the population growth of the United States.
