The Sahara Desert, stretching across North Africa, is the world"s largest hot desert. It encompasses parts of several countries including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, and Tunisia, covering approximately 9 million square kilometers. This vast desert, making up about 31% of Africa, is bounded by the Mediterranean Sea to the north, the Red Sea to the east, the Atlantic Ocean to the west, and the semi-arid Sahel region to the south.

The landscape of the Sahara is predominantly rocky hamada (stone plateaus), with ergs (sand seas with dunes) forming a smaller part of the terrain. The desert features several mountain ranges like the Ahaggar and Tibesti mountains, along with other geographic marvels like the Richat Structure in Mauritania and various volcanic formations. The central Sahara is hyperarid and supports sparse vegetation, while the northern and southern fringes, as well as the highlands, have areas of grassland and desert shrub.

Ecologically, the Sahara is divided into different ecoregions, each with distinct environmental characteristics. The Atlantic Coastal Desert lies along the western Sahara, while the North Saharan steppe and woodlands cover the northern part. The central Sahara Desert ecoregion is vast and supports a variety of xeric (dry) woodlands and montane regions. Plant species have adapted to the arid conditions, and wildlife includes reptiles, birds, and mammals adapted to the desert climate.

Historically, the Sahara was not always a desert. It has alternated between desert and savanna grassland due to changes in Earth"s axis and the North African monsoon over a 20,000-year cycle. Archaeological evidence shows that the Sahara was once a more hospitable place, with petroglyphs indicating that early civilizations thrived in the region thousands of years ago.

The Sahara Desert, the world"s largest hot desert, spans across several countries in North Africa. Each of these nations shares a part of the vast and varied landscape of the Sahara.

The Sahara Desert, the largest hot desert in the world, showcases a diverse climate and environmental features across its expansive area. The Sahara is characterized by two primary climatic regimes: a dry subtropical climate in the north and a dry tropical climate in the south. The subtropical region experiences high annual and daily temperature ranges with cold winters and hot summers, and the precipitation is most common between December and March. Thunderstorms in August can cause sudden flash floods.

In contrast, the southern Sahara enjoys a tropical climate with a strong annual temperature cycle. Winters here are mild and dry, and a hot dry season precedes variable summer rains. The western coastal zone of the Sahara, influenced by the cold Canary Current, maintains a cooler and more uniform temperature.

The Sahara"s landscape is mainly rocky hamada (stone plateaus), with ergs (sand seas with large sand dunes) forming a minor part. Several mountain ranges rise from the desert, including the Ahaggar and Tibesti mountains, with the highest peak being Emi Koussi. The central Sahara is hyperarid and supports sparse vegetation, while the northern and southern reaches have areas of grassland and desert shrub.

Environmental features of the Sahara include vast sand dunes, dry valleys (wadis), dry lakes (oueds), and salt flats (shatts or chotts). The stability of the atmosphere above the Sahara, coupled with the absence of clouds, leads to sunny, dry, and stable weather conditions, with rainfall being virtually non-existent in many regions. This makes the Sahara one of the harshest climates on Earth.
