Algiers vs Valley

Informations

Algiers ( al-JEERZ; Arabic: الجزائر‎; Berber: Dzayer; French: Alger) is the capital and largest city of Algeria. The city's population at the 2008 Census was 2,988,145 and in 2011 was estimated to be around 3,500,000. An estimate puts the population of the larger metropolitan city to be around 5,000,000. Algiers is located on the Mediterranean Sea and at the north-central portion of Algeria.

Algiers is located on the west side of a bay of the Mediterranean Sea. The modern area of the town is built on the level ground by the seashore; the older part, the ancient city of the deys, climbs the steep hill behind the modern city and is crowned by the casbah or citadel, 122 metres (400 ft) above the sea. The casbah and the two quays form a triangle.

A valley is an elongated low area often running between hills or mountains which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period of time. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountain or polar areas. At lower latitudes and latitudes, these glacially-formed valleys may have been created or enlarged during ice ages but now be ice-free and occupied by streams or rivers.

In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valley are described by geographers, using terms that may be global in use or else applied only locally.
