Discusses how rocks change over time, the effects of weathering and erosion on rocks, and how the shifting of tectonic plates affected Earth's structure.
Analiza c?mo las rocas cambian con el tiempo, los efectos de la intemperie y la erosi?n en las rocas, y c?mo el cambio de las placas tect?nicas afect? la estructura de la Tierra.
"From the tops of tall mountains to the rocks in the ground beneath our feet, rocks are always slowly changing. How do they do this? Explore the rock cycle to learn how different kinds of rocks change into each other over many years. Follow along with the different ways rocks form and find out what the changes look like up close"--Provided by publisher.
" . . . images accompany information about metamorphic rocks. The combination of high-interest subject matter and narrative text is intended for students in grades 3 through 8"--Provided by publisher.
" . . . images accompany information about igneous rocks. The combination of high-interest subject matter and narrative text is intended for students in grades 3 through 8"--Provided by publisher.
Introduces children to the earth's rock cycle, explaining how rocks are transformed into one of the three rock classifications, igneous, metamorphic, and sedimentary rocks, and describes the properties of each type.
"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.
