Sand is primarily composed of finely granulated silica and, depending on its location, can include various rock, coral, shell or lava fragments. It is lightweight and easily transported by wind and water. Its composition directly affects its color, resulting in black, white, pink and green coloring.
Wind and water are the primary agents responsible for creating sand. Because it is easily transferred by nature, sand can be found far from its point of creation. When sand is subjected to strong wind, it can build up in large amounts resulting in sand dunes. Sand dunes are seen throughout the desert and on many beaches around the world.Learn More

Sand cools down faster than water because it has a lower specific heat capacity than water. That is, it takes more energy to raise the temperature of water than to raise the temperature of sand by the same amount, given equal masses of each substance. Sand has a specific heat capacity of about 0.290 J/g°C, while water has a specific heat capacity of 4.18 J/g°C.Full Answer >
Sand absorbs water because sand particles have pores in them that, when dry, are filled with air. When the sand particles are wet, the air in the spores is replaced with water.Full Answer >
