Colorful grains of coral constitute much of the sand on tropical beaches (magnification 60x). habitat for a large variety of marine life, which is reflected in the bits and pieces that make their way to nearby beaches. The life forms that inhabit the reefs sequester carbon dioxide from the atmosphere and recycle it into their calcium carbonate shells. Human intervention has significantly reduced the number of these marine organisms, causing the levels of atmospheric carbon dioxide to increase and global warming to worsen.

An iridescent grain of sand was collected from Australia. It's a little fragment of mother-of-pearl (magnification 11 Ox). Precipitated Components Some sand grains, such as ooliths, are formed from the precipitation of calcium in solution. These rounded grains form around a smaller particle that acts as a nucleation site for calcification.
