Water is always flowing, from a brook to a stream, to a river to the ocean. Read and find out more about how water shapes the earth and why it is important to keep our water clean in this fascinating book from author-illustrator Arthur Dorros. This book clearly explains terms like "brook," "stream," "river," and "delta," and the full-color illustrations show where water comes from, how it travels, and where it goes. This is a Stage 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts for children in the primary grades. Let's-Read-And-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
