WebThe formation of sand strips is a long process that involves minerals, water, wind, waves, and tides. It all starts in a mountain or rocky structure located more or less far away from the coast. Eroded sediments are transported from a river or stream and then deposited on the bottom. Eventually, they're channeled to the ocean through river mouths.
