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.
