"From searingly hot deserts to lands of fire and ice, this book is a vivid journey through the natural wonders of the seven continents"--Amazon.

"Earth landforms can look very different from place to place. They can be hilly, flat, or mountainous. Landforms can change their shape with earthquakes, volcanoes, floods, mudslides or erosion. Some of these changes take a long time, and other changes happen quickly. Includes science and reading activities and a word list"--.

Introduces the variety of land formations on Earth, from deserts to mountains to canyons, and describes how they are formed; visits Kenai Fjords National Park in Alaska to show land formations created by glaciers; and presents a hands-on demonstration of moving water's impact on the earth's surface.

Fascinating examination of geologic rocks and rock structures, such as stone pillars, natural bridges, mountains and volcanoes, and their origins, nature, and relevance.

Discusses rock formations and explains the three types of rocks: sedimentary, metamorphic, and igneous. Also defines the terms weathering and erosion. Describes different rock formations including peaks, canyons, mesas and buttes, stacks, monadnocks, and cliffs. Includes a glossary of terms used in the book.

Information about the ways nature and humans are making changes to the landscape around the world, sometimes quickly -- earthquakes or quarrying, sometimes more slowly -- cave formation and erosion or desert reclamation.

Examines geologic structures such as stone pillars, natural bridges, mountains and volcanoes and the processes that shape them.

Explores how scientists and researchers throughout history have attempted to map the landscape of Mars and discusses what their efforts mean to future generations.
