Question

Quizplus · Accepted Answer

Parabolic dunes are crescent-shaped, connected coastal dunes with both tips pointing upwind towards the beach. The shape is formed by vegetation growth and binding of sand, which causes the arms of the crescent to curve backward. Barchan dunes are also crescent-shaped, but they are solitary and found in desert environments. Transverse and longitudinal dunes are linear and not crescent-shaped.
