Determining the Size and Energy of the K-T Asteroid

Summary

A lesson in which students calculate the mass, size, and kinetic energy of the K-T asteroid based on the total abundance of iridium in the K-T boundary layer.

A lesson in which students calculate the mass, size, and kinetic energy of the K-T asteroid based on the total abundance of iridium in the K-T boundary layer. These are the same types of calculations that were done by researchers who first discovered the high amount of iridium in the K-T boundary and provided key evidence for the asteroid-impact hypothesis.
