Difficulty: HardPopulation Distribution and Geography

Australia is one of the most urbanised nations in the world, yet it possesses a vast land area of nearly 7.7 million square kilometres. Considering the continent's physical environment, which of the following best explains why the population is so heavily concentrated in coastal regions rather than being distributed evenly across the continent?

  1. The environmental limitations of the vast, arid interior restrict large-scale human settlement to the more temperate coastal zones with reliable water resources.Answer
  2. B
    The interior of the continent consists of fertile, high-rainfall plains that the government has restricted from development to ensure an even population balance.
  3. C
    National regulations mandate that at least 90% of the population must reside in capital cities to support international trade and maritime security.

Answer

The correct answer is that the environmental limitations of the vast, arid interior restrict large-scale human settlement to the more temperate coastal zones with reliable water resources.
The correct answer identifies that Australia's settlement pattern is driven by the physical environment. Most of the continent's interior is arid or semi-arid, meaning it lacks the rainfall and fertile soil necessary to support large cities. Consequently, the population has clustered in the temperate coastal regions where resources are more abundant.

Step-by-Step Solution

1
Analyze Australia's land area vs. population distribution.
Australia has a very large land area but a relatively small population that is highly concentrated in cities.
To understand the demographic scale.
2
Identify the primary geographic features of the Australian interior.
The interior is largely composed of arid (desert) and semi-arid land.
The climate and terrain directly influence where humans can sustainably live.
3
Evaluate the coastal regions.
Coastal areas typically offer more temperate climates and more reliable access to water.
These factors are essential for supporting large urban centers and agriculture.
4
Connect geography to the urbanisation pattern.
Because the interior is difficult to settle, over 80% of the population lives within 50 kilometres of the coast.
This confirms why Australia is one of the most urbanised nations.

Key Concept

The influence of climate and geography on population distribution

Hints

1
Consider the difference in climate between the center of Australia and the coastal regions.
2
Think about why major cities like Sydney, Melbourne, and Brisbane are located where they are.
3
Recall that much of the Australian 'Outback' is characterized by desert and very low rainfall.
