Desert pavement is when stones are left behind while the rest gets blown away from the wing. Loose sediments wind-swept from the valley horse and deposited in the low lying area. It is gently sloping which extends from the base of the mountains. Mesa is a smaller flat land that is detached from a main land due to lateral erosion of rivers. It is a flat top mountain shaped like a table. It is broad and elevated and has a continuous area coverage.
