Investigate the world of rocks, minerals and fossils with this beautifully illustrated book. Our planet is made of rocks, which in turn are composed of minerals. Find out how different kinds of rocks and minerals are made and how they are used. Discover how fossils formed and the best places to look for them. ‘Spotlight’ illustrations at the bottom of every page encourage readers to look out for easy-to-find rocks and minerals that can be seen in museums or in the countryside.
