sand reflection

Around the world the conposition, the color and even magnetics of the sand are different. The sands I assembled were from the tropics, volvanic island, New England and other areas. In Maui the sand is black dur to the volcanic ash on the island. Howeve, hampton beach sand is full of organism die to the area. The reason is because the Gulf stream brings warm water animals to the area and the Labrador current also affects the area. The grain size is about the same on each beach. Hampton beach howver is more round than maui.
