Are mountains growing taller? Some are. Mount Everest, for example, is the highest mountain in the world. And it is still growing about 1 inch (2.5 cm) every year. In the well received conversational style that sets the Q & A series apart, the Bergers provide a wonderful introduction to Earth science. Children will be eager to explore the changing earth they inhabit. They will learn how rocks are made, what makes a volcano erupt, and that mountains can not only grow taller, but shorter, too!
