Explores the force behind the geological behavior of the planet, including surges of the Earth's axis and their impact on planetary evolution

Have you ever wondered why the Earth is tilted on its axis? This book presents the Reason for the Inclination of the Earth. "The earth has two principal motions, one of revolution about the sun, the other of rotation upon an axis. The revolution about the sun is accomplished in 365 and a quarter days at an average speed of nineteen miles per second, or thirty-three times the speed of the swiftest modern projectile. The rotation upon its axis is accomplished in twenty-four sidereal hours, and since the equatorial circumference of the earth is nearly 25,000 miles, a point on the earth's equator has a speed of rotation of over one thousand miles per hour. In form the earth is an oblate spheroid, a flattened sphere, and the axis about which it rotates coincides very nearly with the shortest axis of the body. If a plane be passed through the center of the earth perpendicular to the axis upon which it rotates, not perpendicular to the shortest axis, this plane will cut the surface in a circle which is known as the equator...

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Encyclopedia of Atmospheric Sciences, Second Edition, Six Volume Set is an authoritative resource covering all aspects of atmospheric sciences, including both theory and applications.

Contains 250 questions and answers about astronomy, particular for the amateur astronomer.

Lean back and settle in for cutting-edge scientific snippets from the trend-setting Dr Karl Kruszelnicki. In Short Back & Science, Dr Karl combs through some of the greatest scientific conundrums of our age, such as what is killing half the bacteria on Earth every two days and why don't mole rats get cancer? Why would anyone pay $40 million for a cup of tea, and how did a toilet seat help to end the First World War? Are bananas really slippery, radioactive and loaded with potassium? What do clouds weigh? And why are there scientists running around naked in the Antarctic? Brushing aside any hype about coconuts and antioxidants, there is no one better to trim down to the facts than Australia's most trusted scientist, Dr Karl. This is a specially formatted fixed layout ebook that retains the look and feel of the print book.
