Hottest Place on Earth

El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit
(57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured. In Death

How far does regular dust blow in the wind
A 1999 study showed that African dust finds its way to Florida and can
help push parts of the state over the prescribed air quality limit for
particulate matter set by the U.S. Environmental Protection Agency. The
dust is kicked up by high winds in North Africa and carried as high as
20,000 feet (6,100 meters), where it's caught up in the trade winds and
carried across the sea. Dust from China makes its way to North America,
too.

World's Highest Waterfall
The water of Angel Falls in Venezuela drops 3,212 feet (979 meters).

Two Great American Cities are Destined to Merge
The San Andreas fault, which runs north-south, is slipping at a rate of
about 2 inches (5 centimeters) per year, causing Los Angeles to move
towards San Francisco. Scientists forecast LA will be a suburb of the
City by the Bay in about 15 million years.

The Largest Volcano on Earth
The Mauna Loa volcano in Hawaii holds the title here on Earth. It rises
more than 50,000 feet (9.5 miles or 15.2 kilometers) above its base,
which sits under the surface of the sea. But that's all volcanic chump
change. Olympus Mons on Mars rises 16 miles (26 kilometers) into the
Martian sky. Its base would almost cover the entire state of Arizona.
