Yes, sand dunes are loose sand carried and deposited by wind from one place to another.
They are a result of deposition.
sand dunes
Sedimentary depositional environment: Area of deposition Alluvial fan: Continental deposits of gravel and sand Sand dunes: Sand mounds in the desert Beach sand: Shoreline deposit of sediments Reef: Calcareous skeleton from organisms build this wave-resistant structure -.-
I believe that erosion removes sand etc. and deposition replaces it. Hurricanes are a prime example of both.
Water vapour depostion is water vapour transforming directly to ice without condensing first.
Sand dunes because, the wind blows sand and some sand hit large rocks, and they fall behind the large rocks, and the large rocks get covered in sand, but soon another large rock will do the same.
Trough Crossbeds are the stereotypical deposit made from fossilized sand dunes. There are however many finer scaled deposits made on the dune such as wave ripples which are only a few sand grains in height.
The two features formed by wave deposition are islands and beaches.
The three features formed by wave deposition is spits, beach, and sandbars.
A sand wave is lots and lots of sand in the ocean when a wave comes.

Breakwaters are made so that waves have a barrier to break on. They help to reduce the force of a wave in an inshore drift and help the sand dunes to stay sloped
Yes.
