The Great Amazon

The Amazon River (Portuguese: Rio Amazonas; Spanish: Río Amazonas) of South America is the largest river in the world by volume, with a total river flow greater than the next top eight largest rivers combined. The Amazon, which has the largest drainage basin in the world, accounts for approximately one fifth of the world's total river flow. During the wet season The Amazon is 120 miles (190 km) - 130 miles (210 km) wide. Because of its enormous dimensions, it is also named The River Sea. At no point is the Amazon crossed by bridges. This is only partly because of its huge dimensions—in fact, for most of its length the Amazon is not so wide that a modern bridge could not span it—but more because, for most of its length, the river flows through tropical rainforest, where there are few roads and even fewer cities.

Great Rivers,the Nile

The Nile (Arabic: النيل‎, transliteration: an-nīl, Ancient Egyptian iteru or Ḥ'pī, Coptic piaro or phiaro) is a major north-flowing river in Africa, generally regarded as the longest river in the world.[1]

The Nile has two major tributaries, the White Nile and Blue Nile, the latter being the source of most of the Nile's water and fertile soil, but the former being the longer of the two. The White Nile rises in the Great Lakes region of central Africa, with the most distant source in southern Rwanda [show location on an interactive map] 2°16′55.92″S 29°19′52.32″E / 2.2822°S 29.3312°E / -2.2822; 29.3312, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia [show location on an interactive map] 12°2′8.8″N 37°15′53.11″E / 12.035778°N 37.2647528°E / 12.035778; 37.2647528, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital Khartoum.

The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population of Egypt and all of its cities, with the exception of those near the coast, lie along those parts of the Nile valley north of Aswan; and nearly all the cultural and historical sites of Ancient Egypt are found along the banks of the river. The Nile ends in a large delta that empties into the Mediterranean Sea.
