The University of Illinois has a well-regarded department of geology with staff members and associates who have created a trove of resources for students and educators seeking to know more about the Earth and its forms. The resources are divided into two dozen topical sections, including Big Bang, Building Blocks of Earth, and Geologic Time. Each section contains links to high-quality resources from the Smithsonian, the National Science Foundation, and other reliable institutions. Additionally, a brief description is available for each item, which is most welcome. The site is rounded out by some classroom materials specifically created by professors within the department.
