geomagnetism

Early fluent readers will explore the science behind the auroras the light the night sky.

"Teaches kids about what the Northern lights are and how the sun and Earth's atmosphere causes them"--Provided by publisher.

Auroras, the dancing lights that most often grace the night skies of the North and South Poles, look like magnificent kaleidoscopes of light and color to the naked eye. This absorbing volume breaks down this breathtaking phenomenon, using it to introduce elementary readers to the basics of magnetism and atmospheric science. The narrative carefully explains how the Earth's poles and atmosphere affect solar wind and describes how similar dazzling displays are visible on other planets. Vivid images capture the wonder of the northern and southern lights, while boxed terms and guiding questions nurture a deeper curiosity about our atmosphere.

"Magnets have amazing power to make things move. But how do they work? What are they used for? Readers will learn the answers to these questions and more through easy-to-read text and vivid photographs. An experiment rounds out the book and provides a hands-on learning experience to encourage deeper understanding"--Provided by publisher.

An introduction to auroras that explains what they are, what they look like, how to find them, and more.

Magnets are all around us, but how do they work? This innovate book delves into that question and many more, showing readers how the pushes and pulls of magnetic force impact both our planet and everyday lives. Informative flowcharts bring magnetism concepts to life giving readers extra incentive to learn more about magnetic materials, how magnets are used in motors, and much more.

Examines animals who sense magnetic fields, including pigeons, rainbow trout, and sea turtles. Features a glossary, a website for further information, and color photographs.

Readers will learn about 500,000 earthquakes happen every year around the world. Most earthquakes are too small for people to notice.

"Page after page, this title proves that the power of attraction is undeniable. Readers move beyond a simple fascination with the power of magnets to a clear understanding of the science behind magnetics. Natural magnets, Earth's magnetic field, and the ties between electricity and magnetics are all featured, in addition to the creation and use of magnets in commercial and everyday applications. Information about the life and work of physicist Joseph Henry, a leading electromagnetics pioneer, and a timeline of important dates in the field are also included" -- Provided by publisher.

Discusses attempts by scientists to explain the dramatic weakening of Earth's magnetic field and contemplates what might happen to the planet if the magnetic field were to vanish.
