Geography

The Greek historian, Herodotus, called ancient Egypt "the gift of the Nile."

According to locals, the Cotopaxi crater looks like a crescent moon.

Ojos del Salado is a dormant volcano.

After the eruption of Avellino in 1995 BC, the volcano passed into a state of more frequent but less dangerous eruptions.

The island is divided into five very large municipalities.

It is made of basalt.

The peaks near Ojos del Salado have been identified as archaeological remains associated with the Inca culture.

The methane gas floats on the water's surface as many tiny bubbles. The density of the resulting gas-water mixture is much less than that of seawater. If a ship finds itself in such an area, due to the lower density, it quickly sinks below the actual sea surface, and the crew is unable even to make an emergency call. The ship sinks.

There are several lakes in the Murray River, Lake Victoria being the most popular.

To circle Uluru, a 3.5 hours walk is required.
