The Oldest and the Newest (A True Book: Extreme Places)

The Earth has been around for a very long time.

Over the billions of years it has existed, Earth has seen constant change, from huge natural changes to the land to human-made constructions. Readers will get an up-close look at these changes, from ancient buildings built thousands of years ago to brand new islands that have formed naturally in recent years. They will also discover how scientists learn about things that happened long before anyone was around to keep records and find out what effects geological changes can have on humans and other life.
