Glaciers are icy giants that come and go with the ice ages. This first look at glaciers explores how they have shaped, and continue to shape, Earth's landscape. From the ice sheets of Antarctica to the glacial basins of the Great Lakes, readers learn about the amazing power of ice on the move. Using concise language and introductory science vocabulary, this book answers questions that curious young scientists wonder about. How do glaciers form? How do glaciers shape Earth? What is their future? Color photographs, fast facts, and a hands-on activity augment the informative text.

Most volcanoes just look like mountains, until bam! They erupt with either smoke and ash or lava. Engaging and accessible text describes and illustrates some of the most common ways that volcanoes form and erupt. Readers will be able to see how Earth's crust moves as plates, revealing the fierce activity of the layer below. Diagrams and cross sections of volcanic activity make the subject clear and easy to grasp. In a simple follow-up activity, readers model a volcanic hot spot in Earth's crust, mimicking the formation of the Hawaiian Islands.
