The Question: Ergs are found in what type of environment?
Also known as sand seas, ergs are areas of deserts which are covered in massive amounts of sand that have little to no vegetation. Generally, these geographic regions are found at the bottoms of enormous basins, where ancient rivers have accumulated sandy deposits. In an erg, the sand is generally loose and is extremely difficult to traverse. The term erg is derived from an Arabic word meaning “dune field.” The Arabian Desert’s Rub’ al Khali (“Empty Quarter”), which covers most of the southern third of the Arabian Peninsula, is the world’s largest erg, covering more than 250,000 square miles of sand.
The correct answer is Desert.
