3. Here you have some activities:

  •  Match the shapes of the dunes with their shapes:

PARABOLIC DUNES / STAR DUNES  / DOME DUNES / LINEAR DUNES 

Crescentic dunes are shaped like crescents, or the shape of a wide letter C. The wide side of a crescentic dune is its windward side, with a small, semi-circular slip face on the other side. Crescentic dunes are the fastest-moving type of dune, and also the most common.

  ……………..form straight or nearly straight lines. Some ………….. are shaped like a wiggling snake, with regular curves. ………………develop where wind pressures are nearly equal on both sides of a dune.

………………have pointed ridges and slip faces on at least three sides. …………. develop where winds come from many different directions. The sand dunes of the Sahara Deserter ergs are ……………

  ……………….are the rarest type of dune. They are circular and do not have a slip face. The wind can blow material onto the dune from any side.

………………….are similar to crescentic dunes. Their shapes are roughly the same, but the slip face of a it its inwardside. ……………………. are also called blowouts, because windsblow out the center of the dune, leaving just a rim on the outside.
