Elegant design combined with beautiful images to explore and explain Earth's natural riches. This is an informative, visually arresting introduction to planet Earth. The core of the book features large, detailed photographs of single objects, many of them small enough to be held in the hand, that each speak volumes about an aspect of Earth's environments and how they work. For example, bubbles of ancient air trapped inside an Antarctic ice core reveal how Earth's climate has changed over time. A piece of pumice thrown several miles into the air by a volcano helps to explain what happens when tectonic plates collide. The book is structured around an imaginary journey that takes the reader from the inner core to Earth's surface (including both land and oceans) and up to the top of the atmosphere. Taking in environments such as grasslands, forests, and reefs, the coverage includes both living and inanimate realms. Feature spreads each throw a spotlight on an iconic place, such as the Amazon Rainforest or the Dead Sea, or a particular process, such as glacial erosion. Many of the most fascinating parts of the natural world are beyond reach. This beautiful, informative book brings them up-close and within our grasp.

We think of them as ordinary objects, but rocks can do

amazing things: there are rocks that glow and rocks that

travel through space, rocks that float and rocks that burn.

These are only some of the surprises in Weird Rocks, a musthave

guide for young rock hounds. Author Michele Corriel

introduces readers to sixteen unusual rocks and explains

the science behind what each one does and how it does it.

Youngsters will discover what makes one kind of rock smell

like a rotten egg, what rock acts like a magnet, and what

rock contains hidden treasure. High-quality photographs,

colorful paintings, and hilarious cartoons add visual delight

to this entertaining and informative book.

Fifty minerals that changed the course of history is a fascinating compendium of the metals, rocks, organic minerals, and gems that have had the greatest impact on the development of human civilization from prehistory to the present day. Entries range from gold – the king of metals and the untarnished symbol of wealth, immortality, and power – to salt, the daily staple that is found in every kitchen and on every dining table, which, at one time, was literally worth its weight in gold. Arranged in chronological order of first use, the entries are judged by their influence in four categories: commercial, practical, cultural, and scientific.

The United States relies on imports for dozens of commodities in everyday use. Often enough, that reliance is 100%. This book provides awareness of the hidden geology and mineralogy behind common things, and develops an appreciation for the global resource distribution that underpins our society. While concerns about oil import reliance are in the news every day, our needs for other minerals are comparable, and are typically unknown even to technologically aware Americans.

Ancient civilizations used the finest stones to set into their idols, decorate their temples, and to adorn themselves. These people used all different sizes and colors of gemstones and these gemstones were set in sliver, gold and other minerals that they made metals. Gemstones made legends of both wealth and history in many parts of the world. Using richly colored gems in trading, inlaying them in jewelry, jeweled crowns, and garments were just a few ways that created that gleam and glitter when rays of light hit a stone. The play of colors giving the gemstones stunning effects. Leaders, kings, priests, medicine men, and others have put many different values on rocks and gemstones. A few of these values are monetary, symbols of great power, healing energies, spiritually and great wealth. In the world today rocks and gemstones are used as they were yet in ancient times and for many of these same reasons. Gemstones both semi-precious and precious are used some way or another by almost every age group, sex and personality. Each stone has a different energy and purpose. In some instances a thrill of excitement is felt by a person just looking at, using or owning a gemstone. Colorful and cut gemstones attract attention because of their beauty and ability to move energy levels and states of mind according to their vibration levels. This statement is also true for all of the uncut stones in the mineral kingdom.
