How Are Earth's Spheres Interacting?

How Are Earth's Spheres Interacting?

This site, part of Exploring Earth Investigation by McDougal Littell and TERC, examines how Earth's spheres are interacting. The investigations "were designed to build students' knowledge of Earth Science concepts�and to raise student awareness of Earth as a system of interconnected components and processes." Here, visitors will find information about Earth's four spheres, how they interact, Earth system processes, and what part human populations play into these systems. Many sections of the site include illustrations and interactive resources to help illuminate the topics covered and the last section is followed by a few links to related resources. This is an excellent site for any Earth Science classroom as an introductory lecture or out-of-class exploration.
