erosion

Rocks break down through the processes of erosion and weathering. Readers will learn through graphic organizers and simple, at-level text what causes erosion and weathering, and how this process is part of the rock cycle. Chapters explore topics such as how erosion and weathering create landforms and form sediment. The human role in erosion and weathering is also explained: both how human actions can exacerbate these processes and steps people take to slow them down. Videos, photographs, and graphic organizers create an enhanced experience in the interactive eBook version. These features supplement the print version with additional high-interest information.
