Saharan dustSaharan dust (also yellow dust, yellow sand, yellow wind or Sahara dust storms) is an aeolian mineral dust from the Sahara desert, the largest hot desert in the world. The desert spans just over 9 million square kilometers, from the Atlantic Ocean to the Red Sea, from the Mediterranean sea to the Niger River valley and the Sudan region in the south. The Sahara is the largest source of aeolian dust in the world, with annual production rates of about 400-700 x 106 tons/year, which is almost half of all aeolian desert inputs to the ocean.
SphinxA sphinx (ˈsfɪŋks , σφίγξ sphíŋks, Boeotian: φίξ phíːks, : sphinxes or sphinges) is a mythical creature with the head of a human, the body of a lion, and the wings of an eagle. In Greek tradition, the sphinx is a treacherous and merciless being with the head of a woman, the haunches of a lion, and the wings of a bird. According to Greek myth, she challenges those who encounter her to answer a riddle, and kills and eats them when they fail to do so. This deadly version of a sphinx appears in the myth and drama of Oedipus.
Great Rift ValleyThe Great Rift Valley is a series of contiguous geographic trenches, approximately in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa. While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of separate though related rift and fault systems. This valley extends northward for 5,950 km through the eastern part of Africa, through the Red Sea, and into Western Asia.
Tropical savanna climateTropical savanna climate or tropical wet and dry climate is a tropical climate sub-type that corresponds to the Köppen climate classification categories Aw (for a dry "winter") and As (for a dry "summer"). The driest month has less than of precipitation and also less than mm of precipitation. This latter fact is in a direct contrast to a tropical monsoon climate, whose driest month sees less than of precipitation but has more than of precipitation.

JewsJews (יְהוּדִים, Yehudim, jehuˈdim) or Jewish people are an ethnoreligious group, nation or ethnos native to the Levant, originating from the ancient Israelites and Hebrews of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, as Judaism is the ethnic religion of the Jewish people, although its observance varies from strict to none. Jews take their origins from a Southern Levantine national and religious group that arose towards the end of the second millennium BCE.
Swahili peopleThe Swahili people (WaSwahili, وَسوَحِيلِ) comprise mainly Bantu, Afro-Arab and Comorian ethnic groups inhabiting the Swahili coast, an area encompassing the Zanzibar archipelago and mainland Tanzania's seaboard, littoral Kenya, northern Mozambique, the Comoros Islands, southwestern Somalia and Northwest Madagascar. The original Swahili distinguished themselves from other Bantu peoples by self-identifying as Waungwana (the civilised ones). In certain regions (e.g.
Wolof peopleThe Wolof people (ˈwoʊlɒf) are a West African ethnic group found in northwestern Senegal, the Gambia, and southwestern coastal Mauritania. In Senegal, the Wolof are the largest ethnic group (~43.3%), while elsewhere they are a minority. They refer to themselves as Wolof and speak the Wolof language, in the West Atlantic branch of the Niger–Congo family of languages. Their early history is unclear.
SavannaA savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to Britannica, there exists four savanna forms; savanna woodland where trees and shrubs form a light canopy, tree savanna with scattered trees and shrubs, shrub savanna with distributed shrubs, and grass savanna where trees and shrubs are mostly nonexistent.
