Given the abundant presence of oil, which is generally thought to come from the fossils of plants and/or tiny marine organisms, the area must once have been densely forested - and that for a very long period of time. But that was at least some 100,000 and probably millions of years ago. Then the climate must have changed to arid and hot, killing the vegetation. And since it was the vegetation that through its roots kept together the good top soil, its dying off caused the fertile soil to be blown away, leaving only sand. The total absence of rivers on the Arab peninsula (apart from a few near the coast) also contributed to the area's dryness.
Why the climate very long ago changed to today's very hot and dry conditions we don't know. Some scientist think that the Arab peninsula breaking loose from the African continent millions of years ago may have had something to do with it.
The largest expanse of desert sand is in the Rub al Khali (Empty Quarter) of the Arabian Desert on the Arabian Peninsula.
The Arabian Desert is larger than all the other deserts except for Antarctica and the Sahara.
The landscapes of the Arabian Peninsula are dominated by vast deserts, such as the Rub' al Khali (Empty Quarter) and the Arabian Desert. These deserts cover much of the region and are characterized by extreme aridity and sand dunes.
The Empty Quarter is the only desert that begins with the letter E. It is the world's largest sand desert and is part of the Arabian desert. It covers the southern portion of the Arabian Peninsula.
The Rub' al Khali or Empty Quarter is the largest sand desert in the world, encompassing most of the southern third of the Arabian Peninsula.
Yes, sand gazelles are wild and exist only on the Arabian Peninsula
Most deserts have areas of dunes. However, the Sahara and Arabian Deserts are probably the best known for their dunes. The Rub al Khali, or Empty Quarter, is the largest sand desert on earth. It is part of the Arabian Desert.
Sand covers around 20-25% of most deserts, with the remainder being made up of rocky, gravelly, or clay-like terrain. Sand dunes are more commonly associated with coastal or wind-blown deserts, such as the Sahara or Arabian deserts.
The Rub al Khali, or Empty Quarter, is the largest sand desert in the world and is located on the Arabian Peninsula in the Arabian Desert.
The Sahara and Great Sand Sea are the largest Egyptian deserts.
sand dunes and steppes =) welcum my homie
