Earth's Spheres Discuss this eTheme.

Learn about the four main spheres of the Earth: lithosphere, atmosphere, biosphere, and hydrosphere. Find out how the Earth has changed since the Pangea times and learn about colliding continents, land masses, formation and destruction of lakes, rivers, mountains, and volcanoes. Learn how scientists use Global Positioning System (GPS) satellite sonograms and ground-probing radars to learn more about the Earth. Includes simulations, animations, videos, games, quizzes, and in-class activities. Also includes eThemes resources on the Earth’s atmosphere, water cycle, and ecosystems.
