The Sphinx has the face of a man and the body of a lion. It stands 240 feet long and 66 feet high. It is carved out of limestone, but so much is unknown. Between its paws is a 15th-century BC stone tablet that tells the story of a vision given to a prince who slept in the shadow of the Sphinx (and perhaps sought its divine aid) and later became a pharaoh through its intercession. Then again, who knows.
Oddly, some geologists say the Sphinx’s weathered condition may not have come from wind and sand, but from RAIN. The Sphinx’s face, especially his nose, was damaged during the French occupation around 1800. Soldiers used it for target practice for their field cannons (although some people say they used rifles to shoot at it.)
If you added American and Europe together they would not be as large as the Sahara Desert. It stretches over Egypt, Algeria, Chad, Libya, Mali, Mauritania, Morocco, Niger, Sudan and Tunisia. In other words, all of North Africa. It is the hottest desert in the world. But about 10,000 years ago, it may have been wet, not dry.
Some sand dunes can be as tall as a 6-story building.
