With a different approach, this series reveals the underlying processes for kids, explaining each region's evolution and illustrating the different forces of nature that have changed the continent over time. The lush forests of the Pacific Northwest, the...

A great introduction to a physical feature of the environment that tells us a great deal about the Earth's geological history, its current state, and the shape of things to come. Difficult concepts and new vocabulary are introduced and made readily accessible in a lively but information-rich narrative that is peppered with vivid imagery and diagrams. Intriguing questions for budding junior geologists to consider round out a title that reveals the...

Earth's resources include things we need for survival. We get heat and light from the sun. We use renewable resources such as wind and sunlight to create power. Earth's crust holds many of the things we need to build our world, as well as the nutrients ne

Diamonds and salt are both minerals, but diamonds are more rare than salt. Curious readers will learn what physical and chemical conditions must be present for minerals to form. They'll discover how minerals are identified and how they are used in daily life. Informative and interesting text presents readers with this science content in a fun way. A graphic organizer shows how different minerals are identified and fact boxes provide readers with exciting...

Almost 20,000 years ago, Earth's climate began to warm. Because of the changing temperatures, a miles-thick ice sheet started to shift. As the ice sheet moved, it carved deep pits in the land and left water in its wake. This melted ice filled the new cavities. This is the story of America's Great Lakes: Superior, Michigan, Huron, Erie, and Ontario. Enriched with stunning photographs and informative fact boxes and sidebars, this educational book sheds...

Igneous rocks form when molten rock cools and hardens. Readers will learn how differences in composition and cooling form different types of igneous rocks. Chapters include graphic organizers to help explain topics such as mountain formation, volcanoes, and how igneous rocks fit into the larger rock cycle.

Learn about types of fossils, how they form, where they are found, and what they teach us about animals and plants. Additional features to aid comprehension include fact-filled captions and sidebars, detailed photographs, infographics or informational diagrams, a table of contents, a phonetic glossary, sources for further research, and an introduction to the author. Did you know that scientists are using crystal shapes to design medicine? Or that...

Young geologists and agriculturalists get an in-depth look at the soil beneath their feet. The book uses photographs to illustrate what soil is, how it's made, what different types of soil there are, and why it's valuable to human life. Using age-appropriate language, the book explains how minerals and different creatures make soil healthy. Young conservationists will also appreciate the final chapters on how erosion and pollution affect soil. Vocabulary,...

The rock cycle has been taking place for millions of years. However, geologists have only known about this phenomenon for about 300 years. Young terrestrial explorers are introduced to different types of rocks, where in the cycle these rocks fit, and where in Earth's layers each step takes place. Fact boxes provide readers with fun additional information. A diagram helps readers make sense of the new information they're learning.

When rocks change because of environmental conditions, the new rocks are called metamorphic rocks. A rock's chemical or physical makeup may change because of conditions such as temperature, stress, or pressure. Your readers will learn fascinating facts including where metamorphic rocks are most commonly found, the different types of metamorphism, and how metamorphic rocks are identified. Full-color photographs depict these rocks in nature. A helpful...
