Overall, however, the Atlas can be categorized as a semi-arid mountain range between the tropical waters of the Atlantic Ocean/Mediterranean and the massive Sahara Desert. The highest mountain in the Atlas is Mount Toubkal. Mount Toubkal measures nearly 14,000 feet, and is located in southwestern Morocco.

Atlas Mountains

Atlas Mountain system in nw Africa, comprising several folded and roughly parallel chains extending 2400km (1500mi) from the coast of sw Morocco to the coast of n Tunisia. North Africa’s highest peak, Djebel Toubkal, 4170m (13,671ft), is found in the Grand Atlas range in w Morocco.

The mountain range separates the Mediterranean and Atlantic coastlines from the Sahara Desert. It has several passes that provide routes between the coast and the Sahara desert. Toubkal, located in Morocco, is the highest peak in the range, and in North Africa. It is 4,167 meters (13,671 feet) high.

Filling nearly all of northern Africa, it measures approximately 3,000 miles (4,800 km) from east to west and between 800 and 1,200 miles from north to south and has a total area of some 3,320,000 square miles (8,600,000 square km); the actual area varies as the desert expands and contracts over time.

Where did the massive amount of the sand that forms the Sahara Desert come from? The sand is primarily derived from weathering of Cretaceous sandstones in North Africa. When these sandstones were deposited in the Cretaceous, the area where they are now was a shallow sea.

Green Sahara: African Humid Periods Paced by Earth’s Orbital Changes. This event is commonly called the “African Humid Period (AHP)”. The AHP was a direct result of African monsoonal climate responses to periodic variations in the Earth’s orbit around the Sun that recur roughly every 20,000 years.

Critics noted that, while some parts of the Sahara Desert were indeed below sea level, much of the Sahara Desert was above sea level. This, they said, would produce an irregular sea of bays and coves; it would also be considerably smaller than estimates by Etchegoyen suggested.

Beneath the sands of the Sahara Desert scientists have discovered evidence of a prehistoric megalake. Buried channels can be detected as much as 50 feet below the surface of the desert. …

Satellite images have revealed the ruins of a long-lost civilisation which existed in what is now the Sahara desert in Roman times and before. He says that satellite pictures show areas of extensive development where nowadays there is nothing but empty desert.

5,000 years ago the Sahara desert was home to people, animals, and lush vegetation. As recently as 5,000 years ago, one of the world’s driest and most uninhabitable places, the Western Sahara desert, was home to a vast river system that would rank as the world’s 12th largest drainage basin if it existed today.

We don’t own the Sahara desert. The Sahara is “owned” by Africans in at least 11 countries. Many of those countries are not exactly paragons of political stability (e.g. Sudan, Egypt, Libya, Sudan, Tunisia).

The name Sahara is primarily a female name of Arabic origin that means Desert. Also a form of Sarah. Name of a desert in Northern Africa.

Sahara as a girl’s name is of Arabic origin meaning “desert”. It is the name of an inhospitable desert in North Africa.

To the south, it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan Region of Sub-Saharan Africa.

Sahara is a desert in Northern Africa as well as a name for women.

Zara is a girl’s name meaning “radiance.” The name Zara has multiple origins, but most notably it is a variation of Zahrah, a name derived from Arabic roots meaning “blooming flower.”

Yes. In fact, there are sand-dunes in Antarctica [1:15].

Antarctica is not a country: it has no government and no indigenous population. Instead, the entire continent is set aside as a scientific preserve. The Antarctic Treaty, which came into force in 1961, enshrines an ideal of intellectual exchange. Military activity is banned, as is prospecting for minerals.

It is a very rough circular shape with the long arm of the Antarctic Peninsula stretching towards South America. There are two large indentations, the Ross and Weddell seas and their ice shelves. In the winter Antarctica doubles in size due to the sea ice that forms around the coasts.
