Answer 1

Answer:

Meander:-

meander. To meander means to wander aimlessly on a winding roundabout course. If you want some time to yourself after school, you might meander home, taking the time to window shop and look around. Meander comes from a river in modern-day Turkey, the Maiandros, which winds and wanders on its course.

Barchan:-

A barchan dune can form when a lot of sand is present in the desert. A steady wind from one direction is needed. The face of a barchan is very steep. As sand escapes over the top of the dune, it forms a trailing wall that is not steep, extending further backward and meeting the desert floor.

Answer 2

Answer:

A barchan or barkhan dune is a crescent-shaped dune. The term was introduced in 1881 by Russian naturalist Alexander von Middendorf, for crescent-shaped sand dunes in Turkestan and other inland desert regions. Barchans face the wind, appearing convex and are produced by wind action predominantly from one direction.
