What Are Sedimentary Rocks? (Let's Rock!)

It all starts with erosion for sedimentary rock. Worn down bits of rock become pressed together under pressure into strata, or layers. The formation of rock such as sandstone, shale, limestone, and dolomite is explained in this fact-filled book. Readers will also learn that this type of rock is useful in determining the Earths geological history because its layers often hold fossils and other geological clues.

Natalie Hyde was born in Fredericton, New Brunswick, and grew up in Galt (now Cambridge), Ontario, where she still lives. She spent most of her childhood collecting crickets, toads and tent caterpillars. The rest of the time she practiced being a genie. When that didn't work out, she studied languages at the University of Waterloo. Natalie lives with her husband and four children in a house with too many stairs, which they share with a little leopard gecko and a cat that desperately wants to eat him. I Owe You One is Natalie's first book for Orca. To learn more about Natalie, please visit www.natalaliehyde.com.
