What is the main difference between erg and reg?
Answer and explanation
Correct answer: Erg is a sand sea while reg is a stony desert surface
The governing concept is that desert surfaces are classified partly by their dominant material. An erg is a broad sand sea made of extensive wind-deposited dunes, whereas a reg is a stony or gravel-covered desert pavement left after finer particles are removed by wind. Therefore option A is correct. The other choices confuse these desert surfaces with river, glacial, coastal, or karst landforms.
