April 20, 2009: Beach Sand
Discover has a series of pictures of beach sand.
The variation in shape and color are amazing by themselves, but Discover also describes how the different grains were created, where and what from. ![]() I was not surprised that some sand comes from rock, but some comes from sea critters and some from pollution. ![]()
