Understanding the kinds of rocks that emerge from the super hot melted rock found beneath Earth's surface is an exciting reading experience. Accessible content allows readers to enhance their science curriculum. A graphic organizer presents the material in an understandable way, as fascinating photographs provide an in-depth...

Sedimentary rocks are created when little pieces of rocks, minerals, and organic matter meld together. This book introduces readers to super sedimentary rocks, such as limestone, coal, and sandstone. Readers will learn about where sedimentary rocks are found, how they're used, and how they fit into the rock cycle. Incredible photographs of sedimentary rocks are paired with accessible hi-lo text to give readers a comprehensive reading experience. Fact...

Metamorphic rocks are a great example of change; they start out as another kind of rock, but change dramatically under high pressure, heat, or another natural force. This book introduces readers to this fascinating part of the rock cycle, using bright color photographs and accessible hi-lo text. Readers will learn about common metamorphic rocks such as schist and marble, including how they were made and how they're used. Graphic organizers and fact...

Igneous rocks are created with magma cools down and crystallizes. This book introduces readers to different kinds of igneous rocks, such as basalt and granite, and explains how such rocks are formed. Readers will also gain a deep understanding of the rock cycle and how igneous rocks fit into it. Detailed color photographs and accessible hi-lo text introduce igneous rocks to readers, while graphic organizers and fact boxes highlight particularly exciting...

From the sand underneath your feet on the beach to the pebbles underneath your shoes on a hiking trail, sedimentary rocks are the most visible type of rock on Earth!
