Summary
"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." -- Publisher's website.
