which is the world longest river?

Answer 1

The river BLUE NILE is a river originating at Lake Tana in Ethiopia. The river is called the Abbay in Ethiopia and the al-Bahr al-Āzraq in Sudan.

Although there are several feeder streams that flow into Lake Tana, the sacred source of the river is generally considered to be a small spring at Gishe Abbai at an altitude of approximately 1800 m (5940 ft). The Blue Nile much later joins the White Nile at Khartoum, Sudan and, as the Nile, flows through Egypt to the Mediterranean Sea at Alexandria. The Blue Nile is so-called because its water is visibly purer for most of the year than the grey-coloured water of the White Nile.

The distance from its source to its confluence is variously reported as 1460 and 1600 km (907 and 1000 mi). The uncertainty over its length might partially result from the fact that it flows through virtually impenetrable gorges cut in the Ethiopian highlands to a depth of some 1500 m (4950 ft)—a depth comparable to that of the Grand Canyon in the United States.

The Blue Nile flows generally south from Lake Tana and then west across Ethiopia and northwest into Sudan. Within 30 km (18.6 mi) of its source at Lake Tana, the river enters a canyon about 400 km long. This gorge is a tremendous obstacle for travel and communication from the north half of Ethiopia to the southern half. The power of the Blue Nile may best be appreciated at Tis Issat Falls, which are 45 m (148 ft) high, located about 40 km (25 mi) downstream of Lake Tana.

The flow of the Blue Nile reaches maximum volume in the rainy season (from June to September), when it supplies about two thirds of the water of the Nile proper. The Blue Nile, along with that of the Atbara River to the north, which also flows out of the Ethiopian highlands, were responsible for the annual Nile floods that contributed to the fertility of the Nile Valley and the consequent rise of ancient Egyptian civilization and Egyptian Mythology. With the completion in 1970 of the Aswan High Dam in Egypt, the Nile floods ended.

The Blue Nile is vital to the livelihood of Egypt. Though shorter than the White Nile, 56% of the water that reaches Egypt originates from the Blue Nile branch of the great river; when combined with the Atbara River, which also has its source in the Ethiopian Highlands, the figure rises to 90% of the water and 96% of transported sediment.[1] The river is also an important resource for Sudan, where the Roseires and Sennar dams produce 80% of the country's power. These dams also help irrigate the Gezira Plain, which is most famous for its high quality cotton. The region also produces wheat, and animal feed crops.

Answer 2

Length: (From White Nile Source to Mouth) 6695km (4184 miles).

Name: The Nile gets its name from the Greek word "Nelios", meaning River Valley.

Sources: The White Nile: Lake Victoria, Uganda. The Blue Nile: Lake Tana, Ethiopia.

Countries: The Nile and its tributaries flow though nine countries. The White Nile flows though Uganda, Sudan, and Egypt. The Blue Nile starts in Ethiopia. Zaire, Kenya, Tanzanian, Rwanda, and Burundi all have tributaries, which flow into the Nile or into lake Victoria Nyanes.

Cities: The major cities that are located on the edge of the Nile and White Nile are: Cairo, Gondokoro, Khartoum, Aswan, Thebes/Luxor, Karnak, and the town of Alexandria lies near the Rozeta branch.

Major Dams: The major dams on the Nile are Roseires Dam, Sennar Dam, Aswan High Dam, and Owen Falls Dam.

Flow Rate: The Nile River's average discharge is about 300 million cubic metres per day. To get a more accurate idea about how much water actually flows in the nile look at this image:

Answer 3

The longest river in the world is the River Nile in the continent of Africa.

Answer 4

Nile, longest river in the world, located in northeastern Africa. From its principal source, Lake Victoria, in east central Africa, the Nile flows north through Uganda, Sudan, and Egypt to the Mediterranean Sea, a distance of 5584 km (3470 mi). From its remotest headstream in Burundi, the river is 6,695 km (4,160 mi) long. The river basin covers an area of more than 2.8 million sq km (1.1 million sq mi).

The Nile (Arabic: النيل‎, translit: an-nīl, Ancient Egyptian iteru, Coptic piaro or phiaro) is a major north-flowing river in Africa, generally regarded as the longest river, though not the most voluminous, 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 2°16′55.92″S, 29°19′52.32″E, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital Khartoum.

Answer 5

Did you know that the longest river in the world is the Nile? Egypt's greatest river is 4,160 miles long! In fact, Africa has two of the ten longest rivers. The Congo, which flows through central Africa, is Number 8 at 2,718 miles long.
What's the second longest river? Why, the Amazon, of course! It is about 4,000 miles from start to finish, winding its way through most of South America.

China lays claim to Numbers 3 and 4: The Yangtze River is 3,964 miles long, and the Huang He is 3,395.

How do we measure these rivers? Geographers calculate the distance from the source of the river to its mouth. For instance, the Ob-Irtysh River, which is Number 5 on the list, is 3,362 miles long from its source in southern Russia to its mouth in the Ob Bay, in the very cold waters off northern Russia.

Russia has two more rivers in the Top Ten. Number 6 is the Amur River, which flows through Siberia and is 2,744 miles long. The Lena River, at Number 7, flows north through central Russia and is 2,734 miles long.

North America's longest river is also Number 9: the Mackenzie, in Canada, at 2,635 miles. Rounding out the Top Ten is the Mekong River, in Southeast Asia, at about 2,600 miles long.

You can see a big difference from Number 1 to Number 10. The Nile is 2,000 miles longer than the Mekong.

Answer 6

River Nile in Egypt is the longest river in the world. For more information go on the following website: en.wikipedia.org/wiki/Longest_river#Nile

Answer 7

Africa's Nile River is the world's longest at 4,160 miles (6,695 kilometers) long. The Blue Nile begins in the highlands of Ethiopia and the White Nile begins at Lake Victoria. The two branches of the Nile merge at Khartoum, the capital of Sudan.

Answer 8

The Nile River in Egypt in the continent of Africa with a length of 6690 km is the longest river in the world.

Answer 9

The Nile is the world's longest river at 4,184 miles. It has two sources, one at Lake Victoria, in Uganda (the White Nile) and one at Lake Tana, in Ethiopia (the Blue Nile).The entire Nile River Delta is estimated to drain an area of 1,293,000 square miles. This area is so vast that is has a number of different climate areas. North, in Egypt and Sudan, rainfall is sparse. More to the south, in and around Ethiopia, rainfall is heavy, contributing to the floodwaters that rush downstream and eventually create the wonderfully fertile soil that supports so much of life in Egypt and Sudan. Dams, the most notable being the Aswan High Dam, have been built along the route to prevent massive flooding of populated areas.

Answer 10

Africa's Nile River is the world's longest at 4,160 miles (6,695 kilometers) long.
The Blue Nile begins in the highlands of Ethiopia and the White Nile begins at Lake Victoria. The two branches of the Nile merge at Khartoum, the capital of Sudan.
