Explanations:Population density is a critical demographic measure that reflects the number of people living in a given area. It is typically expressed as the number of people per square kilometer. Understanding population density helps in comprehending the distribution of people across different regions and can provide insights into urbanization, economic activities, and resource allocation.
Let's examine the regions mentioned in the question:
Sao Paulo (Option A): Sao Paulo is a state in Brazil known for its large urban areas and industrialization. The state has a high population density due to the concentration of people in cities like São Paulo, which is one of the largest metropolitan areas in the world. The dense population in urban centers contributes to a high overall population density for the state.
Himachal Pradesh (Option B): Himachal Pradesh is a state in India located in the Himalayan region. The state is characterized by its mountainous terrain, which limits the amount of habitable land available for settlement. As a result, the population density in Himachal Pradesh is relatively low. The sparse population distribution is due to the challenging topography and limited agricultural land. Therefore, the pair "Himachal Pradesh-dense" is incorrect.
Amazonas (Option C): Amazonas is a state in Brazil that encompasses a significant portion of the Amazon rainforest. The vast forest areas and limited urban development result in a low population density. The sparse population is mainly concentrated in a few urban centers, while the majority of the state remains sparsely populated due to the dense forest cover. This makes the pair "Amazonas-Sparse" correct.
West Bengal (Option D): West Bengal is a state in India with a high population density. The state has large urban areas, such as Kolkata, and fertile plains that support a high population. The combination of urbanization and agricultural activities contributes to a dense population distribution. Therefore, the pair "West Bengal-Dense" is correct.
In summary, the correct answer is Option B, "Himachal Pradesh-dense," because Himachal Pradesh has a sparse population density due to its mountainous terrain and limited habitable areas. Understanding the geographical and demographic characteristics of each region is essential for correctly identifying the population density.
