a geologist is studying a sand dune. the sand dune was formed as wind deposited sand against an obstruction. what process created the sand dune? abrasion deflation weathering compaction

Answer

Brief Explanations:

Abrasion is the wearing - down by friction. Deflation is the removal of loose sediment by wind. Weathering is the breakdown of rocks. Compaction is the squeezing of sediments. Sand dunes form by wind - deposited sand against an obstruction, which is related to deflation as deflation moves sand and then deposition occurs to form dunes.

Answer:

deflation
