What is a long sand dune formed parallel to the wind direction called?
Answer and explanation
Correct answer: Seif dune
A seif dune, also known as a longitudinal or linear dune, is a long, narrow ridge of sand aligned broadly parallel to the prevailing wind direction. It commonly develops where wind flow is persistent or alternates around a dominant resultant direction. Therefore option B is correct. A delta is river sediment, while a cave and beach are coastal features rather than long wind-aligned dunes.
