What are the major geographical facts that are little known?

 There are two rivers Nile: the White Nile and Blue Nile.

The Nile is a major north-flowing river in northeastern Africa, generally regarded as the longest river in the world. It is 6,853 km (4,258 miles) long. The Nile is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.

The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and fertile soil. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.

Let's take a trip from the source of the river to the Nile delta:

What is the weirdest geographical fact that you know?

 Manhattan vs. Iceland

More people (about 80,000 more) live south of 14th Street in Manhattan, New York City than in the whole country of Iceland. This part of Manhattan is roughly only 0.0001% the size of Iceland.

(This picture shows the portion of Manhattan south of 14th Street, a street which starts a bit north of the last bridge to the right of the picture, known as the Williamsburg Bridge.)

Is South America truly due south?

All of South America is east of the city of Detroit in the United States.

The real tallest mountain in the world

Most people think that Mt. Everest is the tallest mountain in the world. But that’s just in relation to sea level. If one measures mountains starting from the plain from which they arise, then Mauna Kea (the biggest volcano on the island of Hawaii) takes the cake, rising at a mighty 33,476 feet (10,203 meters) above the sea floor. That’s about 4,000 feet taller than Mt. Everest, which clocks in at 29,028 feet (8,848 meters) from sea level.

Of Dutch and Belgian exclaves and enclaves

The map below shows the mess of exclaves and enclaves that make the border between Belgium and the Netherlands very complicated indeed. This mess is so bad that the border divides businesses and even some houses, with one part officially in the Netherlands and the other side in Belgium.

A true ancient wonder

The oldest river in the world is the Finke River in Australia, which has been dated to a maximum age of 400 million years old. The below shows the river cutting through extremely old rock, which is part of the proof that the river is very ancient.

One small town indeed!

The whole town of Whittier, Alaska, population 214 people, lives inside the large building below to the right. This includes the mayor’s office, all homes, the schools, the post-office, the chapels, the courthouse, the police and fire departments, and even a tiny jail.
