Emerging readers will be introduced to how rocks form in Earth's crust as well as the three main types of rock in this book supporting natural science education.

Introduces the rock cycle and its impact on Earth, including the three basic forms of rocks, how they are formed, and how they change into each other.

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.

Discover the processes that form everything from the smallest pebbles to the highest mountains.

Some of the rocks we see around us are millions of years old. Rocks don’t stay the same forever, though. Rocks are changing and becoming new rocks all the time. Inside this book, readers will follow a clear, accessible, step-by-step journey through Earth’s rock cycle. They will find out how igneous rock forms from magma following a volcanic eruption. Then they will explore how the igneous rock is eroded by rain to become sediment that eventually forms new sedimentary rock. When Earth’s crust moves, the sedimentary rock is crushed, baked, and transformed into metamorphic rock deep underground. Finally, completing the cycle, the metamorphic rock is heated and melted to once again become magma. Filled with information perfectly suited to the abilities and interests of an early elementary audience, this colorful, fact-filled volume gives readers a chance not only to learn, but also to develop their powers of observation and critical thinking. From stunning photographs to high-interest facts, this book makes learning about Earth’s ever-changing rocks a lively, engaging experience.

Each year, butterflies, whales, and many other animals travel long distances in search of better food, weather, and more. Then they return to repeat the pattern. Learn all about migration, one of nature's amazing cycles.

In this first look at the four seasons of the year, readers learn how their environments change throughout the year and get a glimpse of the science behind the seasons.
