Nick Strobel's Astronomy Notes
This comprehensive astronomy textbook has an entire chapter (Chapter 10, "Solar Fluff") devoted to meteors, meteorites, asteroids, Earth impacts, comets, solar system formation, and newly discovered planetary systems.
Earth Impact Effects Program
An easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. You enter data on the projectile, and the program calculates the probable effects of the impact.
Impact Craters and the Origin of Life
From the Lunar and Planetary Laboratory of the University of Arizona: the environmental effects of impact cratering and the biological consequences of those effects, the origin and evolution of life on Earth, and the
possibility of life elsewhere in the solar system.
Terrestrial Impact Craters page
everything you might want to
know about impact craters; pictures and descriptions of a dozen well-known
craters (with a perfectly awful mistake about the Barringer crater).
