Final answer:
The 5 areas of the world with the lowest population density are: a) Antarctica, Mongolia, Namibia, Iceland, Australia.
Step-by-step explanation:
These areas have the lowest population density due to various reasons. Antarctica, being a frozen continent, has an extremely harsh environment, making it uninhabitable for most of the year. Mongolia's vast steppes and desert areas limit human settlement, while Namibia's arid landscapes and harsh deserts pose challenges for habitation. Iceland's rugged terrain, volcanoes, and a harsh climate restrict large-scale settlement. Australia, despite its size, has a small population primarily concentrated around coastal areas due to its arid interior and harsh conditions.
These regions share common traits contributing to their low population density: extreme climates, inhospitable terrains, and limited resources. While some might have ample landmass, factors like climate, geography, and lack of infrastructure deter significant human settlement, resulting in sparse populations across these areas.
Correct answer: a) Antarctica, Mongolia, Namibia, Iceland, Australia
