SECOND ANSWER
Nile:
Origin: Africa flowing north into the
Mouth: Mediterranean Sea
Basin countries: Sudan, Burundi, Rwanda, DR Congo, Tanzania, Kenya, Uganda, Ethiopia, Egypt
Length: 6,695 km (4,160 mi)
Source elevation: 1,134 m (3,721 ft)

There are two great Tributaries of the Nile: the White Nile, beginning in equatorial East Africa, and the Blue Nile, beginning in Ethiopia. Both branches are on the western flanks of the East African Rift, the southern part of the Great Rift Valley. Another less important one is Atbara which flows only while there is rain in Ethiopia and dries very fast.

Congo:
The sources of the Congo are in the highlands and mountains of the East African Rift, as well as Lake Tanganyika and Lake Mweru, which feed the Lualaba River, which then becomes the Congo below Boyoma Falls. The Chambeshi River in Zambia is generally taken as the source of the Congo in line with the accepted practice worldwide of using the longest tributary, as with the Nile River.

The Congo flows generally west from Kisangani just below the falls, then gradually bends southwest, passing by Mbandaka, joining with the Ubangi River, and running into the Pool Malebo (Stanley Pool). Kinshasa (formerly Léopoldville) and Brazzaville are on opposite sides of the river at the Pool, then the river narrows and falls through a number of cataracts in deep canyons (collectively known as the Livingstone Falls), running by Matadi and Boma, and into the sea at the small town of Muanda.

Lenam Mackenzie:
The Mackenzie River (French: Fleuve Mackenzie) originates in Great Slave Lake, in the Northwest Territories, and flows north into the Arctic Ocean. It is the longest river in Canada at 1,738 km and, together with its headstreams the Peace and the Finlay, the second longest river in North America at 4,241 km in length; only the Mississippi-Missouri is longer. The Mackenzie and its tributaries drain 1,805,200 square kilometers.[1] Its mean discharge is 9,700 cubic metres per second.

FIRST ANSWER (Before you told us the rivers you wanted).
They always flow to a body of water, a lake or the sea or the ocean. So, you may not be able to view an elevation map to tell which direction they flow (higher to lower elevation), but you can look at a regular map and see what body of water they empty into, then you know their direction.

If you would tell us the ten rivers, we could be more specific. You cannot just say all rivers flow north or south, because they do not. You may think most are southerly, but just here in the US:

Answer 2

Nile - North into the Mediteranean
Amazon - East into Atlantic Ocean
Missouri/Mississippi - South into teh Gulf of Mexico
Irtysh - Northwest into the Ob River
Ob River - Generally west then north into the Gulf of Ob
Yangste - East into the East China Sea
Amur - East into the Pacific Ocean
Congo - Southwest into Atlantic Ocean
Huang-Ho - East into the Bohai Sea
LenaLaptev Sea (Artic Ocean) - North into the
Mckenzie - North into Artic Ocean

Answer 3

Most rivers flow south. There are 2 rivers that I can think of that go ''against the flow''. Both the Nile River in Egypt and the Walkill River in the United States flow north.

Answer 4

Just look at which direction the ocean is in. For example, The Mississippi flows south and the Nile flows north.

Answer 5

Just look at it on an elevation map. It will be flowing from the high point to the low point

Answer 6

Hi. Usually considered to be north/south or east/west. It depends on where the outlet is relative to the source. You can find this from a map of the river.

Answer 7

What I would do is take a compass and a toy boy to the rivers and put the boat into the water and hold up the compass and watch which way the boat floats ....

Answer 8

Just looking at Maps doesn't help?
Usually it ends into a sea, an ocean or a vast lake.

Answer 9

They flow from higher elevation to lower elevation, which is usually towards the ocean

Answer 10

throw a peace of wood and watch in which direction it flows.

Answer 11

flow toward ocean
