Quick Answer
An erg is a vast sea of sand dunes. It is one of the major types of desert landscape.
The Full Story
An erg is a large desert area covered mainly by sand and shaped by wind into dunes. Not all deserts are ergs: many are rocky, gravelly, or mountainous instead. Ergs are found in places such as the Sahara, where wind has had enough sand and time to build immense dune fields. They are sometimes called sand seas because their dunes can stretch for hundreds of kilometers.
