Earth's Energy Flow Clara MacCarald

Energy flows all around you. It warms the air and powers our machines. In this book, readers in grades 4-9 will discover how power from the sun journeys to Earth's surface and back out to space. The sun's energy can be reflected, absorbed, used by plants and animals, given off, or trapped to warm the atmosphere. Learn how heat in the atmosphere is rising and what people can do about it. Earth's energy flow affects every living creature on the planet--including you!
