What is another word for seif dune?
Pronunciation: [sˈe͡ɪf djˈuːn] (IPA) 
A seif dune is a particular type of sand dune with a long, narrow ridge which runs parallel to the prevailing wind direction. Synonymous terms for a seif dune include longitudinal dune, linear dune, sandwave dune, and transverse dune. Longitudinal dunes are found in areas with constant wind direction and are usually formed by an extension of linear sand ridges. Whereas sandwave dunes are created when wind direction changes dramatically over time. Transverse dunes, on the other hand, are perpendicular to the wind direction and tend to move faster and simpler in comparison to seif dunes. Understanding the different types of dunes and their synonyms is critical in geography and earth science.
