Underneath the Earth's Crust

In this second book in the Wow! series, you travel to the mysterious core of our planet. For little explorers ages 5 years and up.

From space, the earth looks like a beautiful, colored ball. You immediately see the white clouds, blue oceans, and green, gray, and brown pieces of land. But on the inside, the earth looks very different. Are you also curious about what’s underneath your feet? Is it hot inside the earth? And do animals live there? Travel along to the center of the earth and discover everything about stone caves, geysers, volcanoes, and other magical phenomena under the earth’s crust.
