Rocks : let's investigate
(Book)

"Facts, activities, experiments"--Front cover

Includes index

"All around us Earth's rock cycle is in action. Wind and rain turn rocks to sand; dead leaves mix with rock particles to make soil; over millions of years, layers of sand and soil turn to sedimentary rock; beneath our feet in Earth's crust, extreme heat and pressure create metamorphic rocks; while lava bursts from volcanoes and cools to become igneous rock. This in-depth look at rocks and fossils gives students the chance to carry out investigations such as examining rock properties, building a rock cycle model, and even creating their own fossils"--Publisher
