Question

describe the topography of the सहारा desert

Answer 1

Many of the world’s deserts exhibit vast swaths of flat or gently rolling country cloaked in sparse vegetation. These plains may derive from any number of geologic processes: The flat valleys of the Great Basin of North America, which encompasses the majority of the continent’s true deserts, derive from extensive faulting and are separated by corresponding parallel mountain ranges. The “regs” of the Sahara Desert are windswept gravelly flats. In some deserts, as in some of the drier portions of the Sonoran Desert, a so-called "desert pavement" covers level terrain, comprised of tightly packed, relatively even stones. Such pavements are believed to form over great periods of time as wind action forces fine dust under surface stones, where it accumulates and gradually elevates the cobble above the underlying bedrock.
