OasisIn ecology, an oasis (oʊˈeɪsɪs; : oases oʊˈeɪsiːz) is a fertile area of a desert or semi-desert environment that sustains plant life and provides habitat for animals. Surface water may be present, or water may only be accessible from wells or underground channels created by humans. In geography, an oasis may be a current or past rest stop on a transportation route, or less-than-verdant location that nonetheless provides access to underground water through deep wells created and maintained by humans.

ElephantElephants are the largest living land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea; extinct relatives include mammoths and mastodons. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive grey skin. The trunk is prehensile, bringing food and water to the mouth and grasping objects.

History of NigeriaThe history of Nigeria can be traced to the earliest inhabitants whose remains date from at least 13,000 BC through early civilizations such as the Nok culture which began around 1500 BC. Numerous ancient African civilizations settled in the region that is known today as Nigeria, such as the Kingdom of Nri, the Benin Empire, and the Oyo Empire. Islam reached Nigeria through the Bornu Empire between (1068 AD) and Hausa States around (1385 AD) during the 11th century, while Christianity came to Nigeria in the 15th century through Augustinian and Capuchin monks from Portugal to the Kingdom of Warri.
