Expanding on our popular Let's Explore Science series, this book focuses on erosion. How it's caused, the effects it has on the current landscape, and the way it impacts our Earth are all explained. Great changes take place to form mountains and break apart the land. Erosion carries away broken rocks and soil through a process called weathering. Explore the tremendous ways our planet has changed in this fact-filled book on erosion. This book will allow students to use information from several sources to provide evidence that Earth events can occur quickly or slowly.
