Rocks deform as the result of any number of conditions imposed upon them. Those conditions can vary from the relatively slow collision of continents to the very fast deformation imposed during meteorite impacts. During deformation the rocks respond in a variety of ways, such as by the bending of originally straight layers or fracturing of intact rocks. Deformation can be observed on the microscopic mineral grain scale or on the crustal scale, involving thousands of cubic kilometers. Structural geology is the branch of geology that seeks to describe, analyze and understand the deformation of rocks at all scales. Structural geology research is conducted by Frank Fueten.
