Earth's geosphere is made up of layers: the crust, mantle, and core. The crust is the solid outer layer of Earth and beneath the crust is the mantle, which is solid on top and soft below. The core is at the very center of Earth and made of metals, soft on the outside and solid at the center. Big and small events change the geosphere. Magma from volcanoes creates mountains and other landforms as it cools. Earthquakes cause the crust and upper mantle to shift, creating valleys, waterways, and mountains. Wind blows sand around to create dunes. Erosion of rocks and soil occurs when water, wind, or…mehr

Produktbeschreibung
Earth's geosphere is made up of layers: the crust, mantle, and core. The crust is the solid outer layer of Earth and beneath the crust is the mantle, which is solid on top and soft below. The core is at the very center of Earth and made of metals, soft on the outside and solid at the center. Big and small events change the geosphere. Magma from volcanoes creates mountains and other landforms as it cools. Earthquakes cause the crust and upper mantle to shift, creating valleys, waterways, and mountains. Wind blows sand around to create dunes. Erosion of rocks and soil occurs when water, wind, or ice wears them away, changing the geosphere. Glaciers change the landscape when they carry rocks beneath them that grind down the land underneath. Animals change the geosphere by digging holes in the Earth, making trails, and building dams. Resources that we use to power cars and make batteries and to heat our homes come from the geosphere. The history of Earth is revealed by layers of rocks and fossils in the crust. Pronunciation guide. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
Autorenporträt
Dr. Rebecca Woodbury received her PhD 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 at the Real Science-4-Kids Albuquerque headquarters.
