Sand lies at the bottom of the sea and many lakes. Large amounts of sand wash up from shallow sea bottoms onto beaches and wind may pile up the sand in low hills called dunes.
Sand may be composed of many types of material and is colored according to the mineral it is made of – black sand found in Hawaii consists of grains of basalt and basaltic glass, which are rocks formed from the hardened lava of volcanoes.
The beach is an accumulation of sand, pebbles, or small rocks along a shoreline. Florida's beaches are washed up from shallow sea bottoms. Waves and currents give beaches a variety of shapes – waves along low coasts may build barrier beaches like Miami Beach. Barrier beaches run parallel to the coastline and are separated from the mainland by a sound or lagoon. Spits and hooks stretch out into the water in the shape of a finger or hook. Sedimentary capes, like Cape Canaveral, also extend into the water but are broader than spits and hooks.
