De la idea al libro

If we could take a trip to the center of the Earth, what would we find? In this amazing book readers can do just that with the help of a special ship that can handle the extreme heat and pressure deep beneath Earth’s crust. Digging through a few miles of the crust is just the start of the nearly 4,000-mile journey to Earth’s core. Readers might be surprised to find that not all of the trip is through solid rock, as the intense heat does strange and amazing things to the material that makes up our planet!
