A grain of sand

Adventures in Sand
by David M. Baird

Kids spend lots of time at beaches. But do they ever wonder where all the sand came from? David Baird does, and in his book, he extols the wonders of sand -- how sand is made, why it comes in so many colours, what it can tell us about the earth, and how waves form the sandy ripples we run across.

Good food for thought.

Sand on the Move: The Story of Dunes
by Roy A. Gallant

The text's a bit dry and there aren't enough photos, but this book does tell you some things you may not know about deserts and sand dunes. You'll find out how star-shaped dunes are formed, how dunes bury villages, and why dunes go boom.
