Earth is made up of different layers: crust, mantle, and core. The crust is solid, the mantle is solid on the top and soft below, the core is soft metal on the outside and solid metal in the middle. The crust and solid upper mantle are broken up into huge pieces called plates that float on the soft magma of the lower mantle. The plates are carried along by magma as it moves. The movement of one plate over another can cause mountains to form, as well as creating earthquakes and volcanoes. The movement of plates that slide in opposite directions can cause earthquakes. Plates moving away from…mehr

Produktbeschreibung
Earth is made up of different layers: crust, mantle, and core. The crust is solid, the mantle is solid on the top and soft below, the core is soft metal on the outside and solid metal in the middle. The crust and solid upper mantle are broken up into huge pieces called plates that float on the soft magma of the lower mantle. The plates are carried along by magma as it moves. The movement of one plate over another can cause mountains to form, as well as creating earthquakes and volcanoes. The movement of plates that slide in opposite directions can cause earthquakes. Plates moving away from each other have magma move up between them, causing new crust to be formed as the magma cools and also causing volcanoes and earthquakes. Scientists map the edges of plates by looking for places where mountains, earthquakes, and volcanoes occur. Pronunciation guide. 24 pages filled with engaging, colorful illustrations and diagrams. Reading Level 1-3, Interest Level 2-5.
Autorenporträt
Dr. Rebecca Woodbury received her Ph.D. in biophysical chemistry from the University of New Mexico in 1992. She was awarded a National Science Foundation postdoctoral fellowship in the Department of Molecular Biology at the University of New Mexico, followed by a Burroughs Wellcome Fund Postdoctoral Fellowship in the Department of Molecular Biology at the University of California, Berkeley.While home schooling her three children, Dr. Woodbury was unable to find a curriculum that provided a solid foundation in science. She left academia, and using her scientific background coupled with her love of learning, she developed a series of science books for kids.The Real Science-4-Kids curriculum provides students with a solid foundation in science and gives them the tools to evaluate scientific data on their own. "We should not rely on the 'experts' but instead learn how to critically evaluate every scientific claim," states Dr. Woodbury."In these uncertain times with so many social, scientific, and economic problems, it is not enough to teach our kids what to learn. We must also teach them how to learn, and we must encourage our kids to learn from others. Part of learning from others is to know how to engage in productive debate."The Real Science-4-Kids curriculum, with its engaging, kid-friendly Student Textbooks; Laboratory Notebooks full of real science experiments; and easy to use Teacher's Manuals, provides kids with a solid science education in chemistry, biology, physics, geology, and astronomy. This curriculum is used in all 50 states in the US and many other countries. Dr. Woodbury and her publishing team continue to develop and test new products, including leveled readers and mini books, at the Real Science-4-Kids Albuquerque headquarters.
