Oceans Lakes And Rivers

Almost every stretch of open water on Earth is home to some kind of life. About 97 percent of Earth’s water is salt water. Learn more in Oceans, Lakes, and Rivers, a Focus on Water Science book. In this series readers are introduced to the science behind Earth’s water. A combination of vibrant photography and interesting text encourage readers to learn more about water science.

Provides simple information about the Earth's rivers, lakes, and oceans, including the water cycle, climate, and pollution.

Large bodies of water are all around us: rivers flow through our towns and cities, inland lakes collect pools of fresh water, and the salty ocean covers nearly two-thirds of the Earth’s surface. In this volume, readers will learn about the importance of these three natural sources of water, as well as their similarities and differences. Emphasis is also placed on the relationship between humans and these various water sources, both in terms of constructive use of these precious resources and the risks inherent in pollution. Readers will walk away with a better comprehension of the science behind bodies of water and the delicate balance of the ecosystem.

Discusses the importance of water to planet Earth, including what animals live in water and where the most beautiful bodies of water are.

Introduces the different forms of water in our world; the water cycle; stages in the life of a river; ocean currents, waves, and tides; lakes; and water pollution. Suggested level: intermediate, junior secondary.

Water covers some 75% of the earth’s surface, while land covers 25%, approximately. Yet the former accounts for less than 1% of world GDP, the latter 99% plus. Part of the reason for this imbalance is that there are more people located on land than water. But a more important explanation is that while land is privately owned, water is unowned (with the exception of a few small lakes and ponds), or governmentally owned (rivers, large lakes). This gives rise to the tragedy of the commons: when something is unowned, people have less of an incentive to care for it, preserve it, and protect it, than when they own it. As a result we have oil spills, depletion of fish stocks, threatened extinction of some species (e.g. whales), shark attacks, polluted and dried-up rivers, misallocated water, unsafe boating, piracy, and other indices of economic disarray which, if they had occurred on the land, would have been more easily identified as the result of the tragedy of the commons and/or government ownership and mismanagement. The purpose of this book is to make the case for privatization of all bodies of water, without exception. In the tragic example of the Soviet Union, the 97% of the land owned by the state accounted for 75% of the crops. On the 3% of the land privately owned, 25% of the crops were grown. The obvious mandate requires that we privatize the land, and prosper. The present volume applies this lesson, in detail, to bodies of water.

Oceans and Rivers is part of the comprehensive Questions and Answers series. It asks questions such as: where is the world's highest waterfall?; why are icebergs made of fresh water?; which lake is the biggest?; what is a black smoker?; and where is the deepest part of the ocean?
