Though sand accounts for two percent of our planet’s crust, the Encyclopedia of Earth and Physical Sciences (Marshall Cavendish, 1998) reported that sandy beaches like ours on Hilton Head and Hunting Islands are "relatively rare," "considering how much coastline there is on Earth." Beaches are normally rocky (or, at best, gravelly) strips of land. Most of the world’s sand lies in rivers, desert dunes and on the floors of oceans. |
