Un poema para mis abuelos

The rock cycle has been taking place for millions of years. However, geologists have only known about this phenomenon for about 300 years. Young terrestrial explorers are introduced to different types of rocks, where in the cycle these rocks fit, and where in Earth's layers each step takes place. Fact boxes provide readers with fun additional information. A diagram helps readers make sense of the new information they're learning.

Con este libro mágico podrás dibujar todo lo que quieras: animales, plantas, exploradores, piratas... Y luego puedes borrarlo y volver a dibujar una y otra vez.
