From the back cover: Exploding volcanoes and tearing earthquakes are changing the face of our earth. New islands are born - old ones diappear - huge cracks open in the earth and new lakes appear.
It was once thought the earth's crust was all in one piece - like the skin of an apple. Today, most scientists believe the crust is broken into pieces and that the continents we live on are drifting.
This exciting book explains what earth scientists know about volcanoes and earthquakes. It's better than science fiction - it's science fact.
