Earth is made up of layers: the crust, mantle, and core. The crust is the solid outer layer of Earth. Under the crust is the mantle, which is solid on top and soft below. The core is at the very center of Earth, is made of metals, and is soft on the outside and solid at the center. The crust and solid upper mantle are broken up into huge pieces called plates, which are carried along by movement of magma in the lower mantle. The place where the edges of two places meet is called a fault and is where earthquakes occur. As two plates move next to each other, the rough edges can get stuck…mehr

Produktbeschreibung
Earth is made up of layers: the crust, mantle, and core. The crust is the solid outer layer of Earth. Under the crust is the mantle, which is solid on top and soft below. The core is at the very center of Earth, is made of metals, and is soft on the outside and solid at the center. The crust and solid upper mantle are broken up into huge pieces called plates, which are carried along by movement of magma in the lower mantle. The place where the edges of two places meet is called a fault and is where earthquakes occur. As two plates move next to each other, the rough edges can get stuck together. When the plates let go at a fault, the sudden movement of the ground causes an earthquake. Earthquakes cause seismic waves, which are vibrations that transfer energy through the Earth from the source of the earthquake. When we feel an earthquake, we are feeling the vibration of the seismic waves. Earthquakes can be big and cause much damage or can be small. By studying earthquakes, geologists can learn about how Earth works and what the inside of Earth is like. Pronunciation guide. 24 pages filled with engaging, colorful illustrations. 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 engaging, kid-friendly curriculum provides 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 for both home school and public school students.
