What You'll Learn
The Sahara is the world's largest hot desert
The desert covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Niger, Western Sahara, and Sudan, as well as parts of southern Morocco and Tunisia. To the north, it skirts the Mediterranean Sea in Egypt and Libya, and to the south, it is bounded by the Sahel, a semi-arid tropical savanna around the Niger River Valley and the Sudan region of sub-Saharan Africa.
The Sahara is characterised by its hyper-arid central region, with sparse vegetation and a near-total absence of rainfall. This is due to its location in the subtropical ridge, a belt of semi-permanent subtropical high pressure where air from the upper troposphere descends, warming and drying the lower atmosphere and preventing cloud formation. As a result, the weather in the Sahara is consistently sunny, dry, and stable.
Despite the extreme aridity, the Sahara does support some life. Many organisms have adapted to the harsh environment, such as herbaceous plants that complete their life cycles in the brief period after a heavy rain. Some animals, like the desert snail, survive through estivation, a period of dormancy triggered by extreme environmental stress. Humans have also lived in the Sahara for millennia, with archaeological evidence indicating that ancient Saharan lakes once supported fishing communities. More recently, nomadic pastoralists have herded livestock, while sedentary agriculturalists have cultivated crops in oases.
The Sahara has not always been a desert, and it is believed that it has alternated between desert and savanna grassland over hundreds of thousands of years due to the Earth's axial precession. This 20,000-year cycle has caused the North African monsoon to shift locations, resulting in periodic changes to the region's climate.

Australia is a country, the Sahara is a desert
Australia is a country, a sovereign nation with a defined territory and a population of over 25 million people. It is a large island surrounded by oceans, with a land area of about 7.69 million square kilometres (2.97 million square miles). Australia is part of the Oceania region and is the sixth-largest country in the world by total area. It is unique in that it is both a country and a continent, with a diverse range of landscapes, from urban cities to vast Outback deserts. The country is known for its natural wonders, unique wildlife, and cultural attractions, making it a popular tourist destination.
On the other hand, the Sahara is not a country, but a desert. It is a vast arid region covering much of North Africa, encompassing territories of several countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, and Tunisia. The Sahara is not a single entity with defined borders like a country but rather a continuous stretch of desert with varying terrain.
In terms of size, the Sahara is roughly comparable to Australia. The Sahara Desert covers around 9.2 million square kilometres (3.6 million square miles), slightly larger than the total area of Australia. This makes the Sahara the largest hot desert and the third-largest desert in the world, after Antarctica and the Arctic. However, despite their similar sizes, the Sahara and Australia offer starkly contrasting landscapes and environments.
While Australia is a diverse country with varied terrain, the Sahara is predominantly an arid to hyper-arid desert, consisting of vast stretches of sand dunes, stone plateaus, and dry valleys. The Sahara is known for its extreme temperatures, scarce precipitation, and challenging living conditions. In contrast, Australia has a varied climate, ranging from tropical rainforests in the north to more temperate climates in the south, with snow-capped mountains and ski resorts.
The distinction between the two also lies in their human presence and cultural significance. Australia is a developed country with a high standard of living, modern infrastructure, and a vibrant culture that blends Indigenous heritage with diverse international influences. On the other hand, the Sahara has a sparse population, with most inhabitants being nomadic or semi-nomadic, practising transhumance and adapting to the harsh desert conditions. The Sahara has a rich history, having played a significant role in trade routes, and is associated with a unique blend of cultures and traditions found in the surrounding countries.

The Sahara spans 9,200,000 square kilometres
The Sahara is a vast desert spanning 9,200,000 square kilometres (3,600,000 sq mi) across North Africa. It is the world's largest hot desert and the third-largest desert overall, after Antarctica and the northern Arctic. Covering 31% of the African continent, the Sahara is a formidable expanse of arid land, with sparse vegetation and a harsh climate.
The desert's boundaries stretch from the Red Sea in the east to the Atlantic Ocean in the west, and from the Mediterranean Sea in the north to the Sahel in the south. This semi-arid tropical savanna acts as a buffer zone, marking the southern extent of the Sahara and separating it from the more temperate savanna biomes beyond. The Sahara's landscape is diverse, ranging from sand dunes over 180 metres (590 ft) high to stone plateaus, gravel plains, dry valleys, and salt flats.
The Sahara is not a static environment but has alternated between desert and savanna grassland over hundreds of thousands of years due to the precession of the Earth's axis. This cyclical transformation has resulted in a rich archaeological record, indicating that ancient Saharan lakes once existed, providing a habitat for humans to live, hunt, and fish. Today, the Sahara is divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, and the Libyan Desert, each with its unique geographical features.
The Sahara's immense size and arid conditions present a challenging environment for human habitation. However, people have adapted to life in the desert for thousands of years, employing strategies such as nomadic pastoralism, sedentary agriculture in oases, and trade along caravan routes. Despite the harsh conditions, the Sahara supports some life, including herbaceous plants that complete their life cycles rapidly after rare rainfall events and animals that survive through estivation, a period of dormancy triggered by extreme environmental stress.

Australia is 7,692,024 square kilometres
The Sahara Desert is a vast and iconic landscape, but how does it measure up to Australia in terms of size? To put it into perspective, the Sahara Desert covers a total area of around 9,200,000 square kilometres (3,552,140 sq. mi), spanning across Northern Africa. In comparison, Australia, the sixth-largest country in the world, has a total land area of about 7,692,024 square kilometres (2,969,907 sq. mi). This means that the Sahara Desert is roughly 1.2 times larger than Australia.
Despite Australia being smaller in size, it boasts a diverse range of landscapes, from its expansive Outback to its metropolitan coastal cities. The country is surrounded by oceans, with a coastline stretching over 35,877 kilometres (22,293 mi), offering a unique contrast to the arid Sahara. While the Sahara is renowned for its sand dunes and arid climate, Australia presents a varied terrain, including rainforests, mountains, and deserts.
The Sahara's immense size becomes evident when comparing it to individual Australian states or territories. For instance, the Sahara is larger than the Australian state of New South Wales, which covers 800,642 square kilometres (309,129 sq. mi), or Victoria, which spans 227,416 square kilometres (87,806 sq. mi). In fact, the Sahara is so vast that it could fit within its boundaries multiple Australian states or territories, such as Queensland (1,852,642 sq. km/715,309 sq. mi), Western Australia (2,529,875 sq. km/976,790 sq. mi), and the Northern Territory (1,349,129 sq. km/520,902 sq. mi).
While the Sahara and Australia differ in geographical features and land use, their sizes provide an interesting perspective on the world's vast and varying landscapes. The Sahara, with its seemingly endless expanse of sand, serves as a reminder of the planet's arid regions, while Australia, with its unique mix of urban and natural environments, showcases the diversity found within its smaller land area. Both regions present a fascinating exploration of Earth's geography and the varying scales of its ecosystems and landforms.
To put it into context, the size of Australia in square kilometres, which is 7,692,024, is comparable to other large countries or regions. For example, Australia is slightly smaller than Brazil, which has a land area of 8,515,767 square kilometres (3,287,955 sq. mi), and is significantly larger than India, which covers 3,287,263 square kilometres (1,269,219 sq. mi). Australia's size also surpasses that of the European Union, which, with its 27 member states, has a combined area of 4,233,255 square kilometres (1,634,469 sq. mi).

The Sahara covers 31% of the African continent
The Sahara is a vast expanse of desert spanning 9,200,000 square kilometres (3,600,000 sq mi) across North Africa. It is the largest hot desert in the world and the third-largest desert overall, only surpassed by the deserts of Antarctica and the northern Arctic. Covering approximately 31% of the African continent, the Sahara is a dominant geographical feature of the region.
The desert landscape is characterised by rocky hamadas (stone plateaus), ergs (sand seas), sand dunes, dune fields, stone plateaus, gravel plains, dry valleys, lakes, and salt flats. The Sahara also encompasses several mountain ranges, including the Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, and the Saharan Atlas. The highest peak within the Sahara is Emi Koussi, a shield volcano located in the Tibesti range of northern Chad.
The Sahara's boundaries extend from the Red Sea in the east to the Mediterranean Sea in the north and the Atlantic Ocean in the west. To the south, the Sahara is bordered by the Sahel, a semi-arid tropical savanna that surrounds the Niger River valley and the Sudan region of sub-Saharan Africa. This southern boundary marks the transition from the harsh desert conditions of the Sahara to the more temperate savanna biomes beyond.
The Sahara's immense size is not static but rather subject to change over time. It has alternated between desert and savanna grassland in a cycle of approximately 20,000 years, influenced by the precession of the Earth's axis as it rotates around the Sun. This cyclical change affects the location of the North African monsoon, resulting in fluctuations in the Sahara's aridity and vegetation patterns.
The Sahara covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Niger, Western Sahara, and Sudan. It also extends into southern Morocco and Tunisia. The desert's presence has undoubtedly shaped the cultural and historical landscape of these regions, with human settlements and adaptations dating back to ancient times.
