Why are sand dunes commonly found along the coast A there is a lot of wind to carry the particles B The salt in the water is needed to hold the sand together C moving water is needed to deposit the particles on the river bed D heavy wave action is needed to move the sand

Answer 1

The correct answer is A: there is a lot of wind to carry the particles.

Sand dunes are formed by the accumulation of sand, which is typically carried and shaped by wind. Coastal areas often have a lot of loose sand and strong winds, making it conducive for the formation of sand dunes.
