1 Insertion â when a base is added to the sequence. 2  Deletion â when a base is deleted from the sequence.  Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. These regions of DNA can be between 10,000 and 5,000,000 bases long.
Wind deposition can result in dunes and loess deposits.
The following two video clips (part I and part II) demonstrate different types of wind erosion and the relationship of soil texture to the types of wind erosion. Part I. This video clip explains the three types of wind erosion, (saltation, surface creep, and suspension). Video Clip by Dr. John Tatarko, USDA. This video clip explains the relationship of soil texture to type of wind erosion (saltation, surface creep or suspension).
