FREAKY FACTS... A few grains of truth

1) Sand is classified as any sediment between 0.125 and 2.0mm and is measured by using sieves.

2) A child’s beach bucket holds 3,500,000,000 grains of sand.

3) You can hunt treasure along the coast of Namibia in south-west Africa because there are teeny diamonds in the sand.

4) Someone who collects sand is called an arenophile.

5) The grains are green in Guam. The sand’s hue comes from olivine, a mineral found in basalt lava. The waves around the island wash out the lighter grains of sand, leaving the denser olivine crystals to create the green beach.
