erosion

"Introduces readers to the science behind erosion and weathering. Readers will dig deep to uncover the many forces that impact the shape of the earth, including wind, water, and living creatures."--Publisher.

Sing along while exploring some of Earth's most amazing sights and find out how wind and water shape the land. Includes CD and online music access.

Examines three different types of rock and how each is formed. A visit to the Grand Canyon illustrates how geologists discern clues to Earth's history by studying the composition of rock layers that have eroded over millions of years.

Erosion can make slow, almost invisible modifications, or sudden, drastic alterations to the landscape. Either way, the forces of erosion will always be at work.

Explains how water, rain, snow and wind constantly reshape the surface of the Earth, and describes how physical weathering, chemical weathering, and erosion occur.

This volume breaks down the rock cycle step by step, including brief explanations of the three kinds of rocks, erosion, and many key terms.

Readers learn the specifics of how erosion happens and its place in the rock cycle in this book.

Most people don't think about the soil under their feet, but basic dirt can reveal a lot about Earth's past. Soil is formed from tiny grains of rock that existed many years ago. It can also form in the wake of landslides, volcanoes, and everyday weathering. This text takes readers underground to examine Earth's many kinds of soil, the microorganisms and inorganic matter that make it up, and the critical role it plays in ecosystems around the world. Helpful diagrams, fact boxes, and sidebars support the information-rich text, which supports elementary science curricula, and colorful images will keep readers engaged from start to finish.

"Earth is constantly changing. Wind, water, and even humans change Earth's surface. The land is broken down and worn away by erosion. The Grand Canyon was made from erosion. Many other landforms were made this way, too."--Provided by publisher.
