Abuja () is the capital city of Nigeria situated in the centre of the country within the Federal Capital Territory (FCT). It's a planned city and was built mainly from the 1980s, replacing the nation's most populous city of Lagos as the capital on 12 December 1991. Abuja's geography is characterized by Aso Rock, a 400-metre (1,300 feet ) monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the city extend into the south of the rock. Zuma Rock, a 792-metre (2,598 feet ) monolith, lies just north of the city on the expressway to Kaduna.
At the 2006 census, the city of Abuja had a population of 776,298 which makes it among the ten most populous cities in Nigeria. According to the United Nations, Abuja climbed by 139.7% between 2000 and 2010, which makes it the fastest growing city in the world.
As of 2015, the town is experiencing an annual growth of 35%, retaining its position as the weakest city on the African continent and among the fastest-growing in the world.

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%.
Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.
