Earth's landscape can be vastly different from region to region, and it's always changing! The shifting plates on which the planet's crust sits cause some areas to rise, while others sink. The Dead Sea in the Middle East is the lowest dry place on Earth, about 1,300 feet (396 m) below sea level. In the ocean, Challenger Deep is home to some creepy marine life, much different than anything we see near the surface. These interesting places and others are featured in this book, which interweaves intriguing science and social studies subject matter with many fun facts.
