You see sand in lots of places: the beach, on the playground, in
gardens, as part of buildings. We even talk about sand in our eyes. But what
about sand in windows and computers? Did you know that sand is the second most
common element on earth (oxygen is first). Sand is likely to be more important than you
ever dreamed of.

Sand is used in manufacturing, whether to sand down items or build
them. Sand is used in energy, such as the oil industry. Sand is used in
science: archeology, chemistry, physics, oceanography, and so on. Sand is part
of the tourist industry too. The jobs associated with sand may be as numerous
as the grains of sand on the beach!
