Understanding Sea Sand 1. Characteristics of Sea Sand. Sea sand is obtained from beaches, tidal areas, and sea floors. Its characteristics include: Granular Texture: Sea sand typically has a granular texture with a mixture of coarse and fine particles.; Salt Content: It often contains high levels of salt and other minerals due to its proximity to seawater.
