Overview
You’re splashing around in the ocean on a hot day when you accidentally swallow a mouthful of salty seawater. Yuck! The water that comes out of a faucet doesn’t taste salty. If you catch raindrops on your tongue, they don’t taste of salt either. So what makes seawater taste salty? Readers will discover how tiny particles of salt from rocks on land are carried into Earth’s oceans by rivers, and washed into the sea by ocean waves. They’ll also learn the answers to these questions: Why is the ocean salty and rivers are not? How do underwater volcanoes help make oceans salty? Why is it unsafe to drink salt water? And how is the salt that we use to flavor our food taken from the sea? Filled with information perfectly suited to the abilities and interests of an early elementary audience, this colorful, fact-filled volume gives readers a chance not only to learn, but also to develop their powers of observation and critical thinking. With its stunning photographs and surprising and high-interest facts, this book makes learning about water an engaging experience
