Text and photographs describe bodies of water, such as oceans, lakes, and rivers, as well as land forms such as mountains, island, valleys and plains.

Provides comprehensive information on the interrelationships of the natural world, environmental problems both natural and man-made, the relative risks associated with these problems, and solutions for resolving and/or preventing them.

How do clouds form, and where does water go after it rains? What makes water stick to things, and does this characteristic serve any purpose? What effect does pollution have on the quality of water—for humans and other living things? Can salt water be made drinkable? Is it possible to change aspects of water such as its freezing point or density? Using simple and fun hands-on experiments, you can answer all of these questions and more as you learn about the substance that makes life possible on Earth—water.

An essential tool to teach kids about the importance of water! Did you know that water covers almost three-fourths of Earth’s surface? More than half the world’s creatures live in this water. And the rest cannot survive without it! That’s why it is so important to protect this vital resource, which has been threatened by pollution and other human-made dangers. Discover more about what is threatening Earth’s most precious resource, as well as what is being done to protect it, in Protecting Earth’s Waters. ABOUT THE SERIES: Earth is known as the Blue Planet because of the abundant amount of water that covers our home. And nothing on Earth could survive without it. As we find ourselves facing a global water crisis, learning about this life-giving resource has never been more important. The books in this series are filled with colorful photos and diagrams, plus easy-to-digest text, and fascinating facts. And they offer young readers an in-depth look at what water is, how we use it, and most importantly, what we can do to protect it.

From lakes, to clouds, to rain that falls back to Earth—discover how water changes through various processes to form the water cycle.

The compelling and adventurous stories of seven pioneering scientists who were at the forefront of what we now call climate science. From the glaciers of the Alps to the towering cumulonimbus clouds of the Caribbean and the unexpectedly chaotic flows of the North Atlantic, Waters of the World is a tour through 150 years of the history of a significant but underappreciated idea: that the Earth has a global climate system made up of interconnected parts, constantly changing on all scales of both time and space. A prerequisite for the discovery of global warming and climate change, this idea was forged by scientists studying water in its myriad forms. This is their story. Linking the history of the planet with the lives of those who studied it, Sarah Dry follows the remarkable scientists who summited volcanic peaks to peer through an atmosphere’s worth of water vapor, cored mile-thick ice sheets to uncover the Earth’s ancient climate history, and flew inside storm clouds to understand how small changes in energy can produce both massive storms and the general circulation of the Earth’s atmosphere. Each toiled on his or her own corner of the planetary puzzle. Gradually, their cumulative discoveries coalesced into a unified working theory of our planet’s climate. We now call this field climate science, and in recent years it has provoked great passions, anxieties, and warnings. But no less than the object of its study, the science of water and climate is—and always has been—evolving. By revealing the complexity of this history, Waters of the World delivers a better understanding of our planet’s climate at a time when we need it the most.

Times are tough for shrimpers and fishers in the Gulf of Mexico. The animals they rely on for their livelihood are harder to find. Every summer a dead zone—a region of low oxygen—emerges in the waters along the Gulf Coast. Where oxygen is low, fish and others animals cannot survive. Currently the world has more than 400 identified dead zones, up dramatically from the 49 dead zones identified in the 1960s. The good news is that people can eliminate dead zones by changing agricultural practices and reducing pollution. Using real-world examples, this book looks at the impact of pollution on global water resources, and discusses the interconnectedness of ecosystems and organisms.
