Accra ghana dating

The southwestern, northwestern, and extreme northern parts of the country consist of a dissected peneplain (a land surface worn down by erosion to a nearly flat plain, later uplifted and again cut by erosion into hills and valleys or into flat uplands separated by valleys); it is made of Precambrian rocks (about 540 million to 4 billion years old).Most of the remainder of the country consists of Paleozoic deposits (about 250 to 540 million years old), which are thought to rest on older rocks.Most of the other rivers, such as the Pra, the Ankobra, the Tano, and a number of smaller ones, flow directly south into the ocean from the watershed formed by the Kwahu Plateau, which separates them from the Volta drainage system.South of Kumasi, in the south-central part of the country, is Ghana’s only true natural lake—Bosumtwi—lying in a meteorite impact crater and without any outlet to the sea.Although trading was originally centred on the gold that was readily available in the area (and from which the future British colony the Gold Coast would take its name), the focus shifted to the lucrative slave trade in the 17th century.The area later became known for growing cacao, the source of cocoa beans.The only extensive areas of young rocks less than about 136 million years old are in the wide, lagoon-fringed delta of the Volta, about 50 miles (80 km) east of Accra, and in the extreme southwest of the country, along the Axim coast.

The drainage system is dominated by the Volta River basin, which includes Lake Volta.

Ghana, country of western Africa, situated on the coast of the Gulf of Guinea.

Although relatively small in area and population, Ghana is one of the leading countries of Africa, partly because of its considerable natural wealth and partly because it was the first black African country south of the Sahara to achieve independence from colonial rule.

Along the coast are numerous lagoons, most of them formed at the mouths of small streams.

Over much of the surface of Ghana, the rocks are weathered, and great spreads of laterite (red, leached, iron-bearing soil) and lesser spreads of bauxite and manganese are found on the flat tops of hills and mountains.
